This homepage is dedicated to my mom, who died at April 9, 2020 in the age of 93 years. In retrospect, the proposed solution concepts of different problem areas (the Riemann Hypothesis & the inconsistent quantum theory with Einstein's gravitation theory) originate in some few simple common ideas / basic conceptual changes to current insufficient "solution attemps".

Part A: A Kummer function based Zeta function theory

Part B: A Hilbert space based quantum gravity model

Part C: Linkages between the quantum gravity model and philosophy.

(A) A Kummer function based Zeta function theory

An alternative Kummer function based Zeta function theory is proposed to enable

(a) the verification of several Riemann Hypothesis (RH) criteria

(b) a truly circle method for the analysis of binary number theory problems.

The Kummer function based Zeta function theory is basically about a replacement of the integral exponential function Ei(x) by a corresponding integral Kummer function. It enables the validation of several RH criteria, especially the "Hilbert-Polya conjecture", the "Riemann error function asymptotics" criterion and the „Beurling“ RH criterion. The latter one provides the link to the fractional function and its related periodical L(2) Hilbert space framework, (TiE).

Regarding the tertiary Goldbach problem Vinogradov applied the Hardy-Littlewood circle method (with its underlying domain "open unit disk") to derive his famous (currently best known, but not sufficient) estimate. It is derived from two estimate components based on a decomposition of the (Hardy-Littlewood) "nearly"-circle into two parts, the „major arcs“ (also called „basic intervals“) and the „minor arcs“ (also called „supplementary intervals“). The „major arcs“ estimates are sufficient to prove the Goldbach conjecture, unfortunately the „minor arc“ estimate is insufficient to prove the Goldbach conjecture. The latter one is purely based on "Weyl sums" estimates taking not any problem relevant information into account. However, this estimate is optimal in the context of the Weyl sums theory. In other words, the major/minor arcs decomposition is inappropriate to solve the tertiary and the binary Goldbach conjecture.

The primary technical challenge regarding number theoretical problems is the fact that only the set of odd integers has Snirelman density ½, while the set of even integers has only Snirelman density zero (because the integer 1 is not part of this set).

The additional challenge regarding binary number theoretical problems is the fact that the problem connects two sets of prime numbers occuring with different density (probability) during the counting process; regarding the Goldbach conjecture this concerns the fact, that the number of primes in the interval (2n-p) is less than the number of primes in the interval (1,p). Therefore, two different „counting methods“ are required to count the numbers of primes in the intervals (1,p) and (p,2n-p).

In order to overcome both technical challenges above a truly circle method in a Hilbert space framework with underlying domain „boundary of the unit circle“ is proposed. The nonharmonic Fourier series theory in a distributional periodic Hilbert scale framework replaces the power series theory with its underlying domain, the "open unit disk".

The proposed nonharmonic Fourier series are built on the (non-integer) zeros of the considered Kummer function, (which are only imaginary whereby for their real parts it holds >1/2) replacing the role of the integers of exp(inx) for harmonic Fourier series. They are accompanied by the zeros of the digamma function (the Gaussian psi function). The set of both sequences are supposed to enable appropriate non-Z based lattices of functions with domain "negative real line & "positive" critical line". This domain is supposed to replace the full critical line in the context of the analysis of the Zeta function, in order to anticipate the full information of the set of zeros of the Zeta function (including the so-called trivial zeros), while omitting the redundant information provided by the critical zeros from the zeros from the "negative" part of the critical line.

With respect to the analysis of the Goldbach conjecture it is about a replacement of the concepts of trigonometric (Weyl) sums in a power series framework by Riesz bases, which are "close" (in a certain sense) to the trigonometric system exp(inx). The nonharmonic Fourier series concept of almost periodic functions is basically about the change from integers n to appropriate sequence a(n). Such a change also makes the difference between the Weyl method and the van der Corput method regarding exponential sums with domains (n,n+N), (GrS), (MoH). Selberg‘s proof of the large sieve inequality is based on the fact, that the characteristic functions of an interval (n,n+N) can be estimated by the Beurling entire function of exponential type 2*pi, applying its remarkable extremal property with respect to the sgn(x) function, (GrS).

The Riesz based nonharmonic Fourier theory enables the split of number theoretical functions into a sum of two functions dealing with odd and even integers separately, while both domains do have Snirelman density ½. In case of an analysis of the Goldbach conjecture it also enables the definition of two different density functions, „counting“ the numbers of primes in the intervals (1,p) resp. (p,2n-p).

The trigometric system exp(inx) is stable under sufficienctly small perturbance, which leads to the Paley-Wiener criterion. Kadec's 1/4-theorem provides the "small perturbance" criterion, which is fulfilled for both sets of zeros, the considered Kummer function and the digamma function. A striking generalization of "Kadec's 1/4-theorem", (YoR) p. 36, with respect to the below is Avdonin's "Theorem "1/4 in the mean", (YoR) p. 178.

The Fourier transformed system of the trigonometric system forms an orthogonal basis for the Paley-Wiener Hilbert space (PW space), providing an unique expansion of every function in the PW-space with respect to the system of sinc(z-n)-functions. Therefore, every PW-function f can be recaptured from its values at the integers, which is achieved by the cardinal series representation of that function f (YoR) p. 90.

When the integers n are replaced by a sequence a(n)) the correspondingly transformed exponential system builds a related Riesz basis of the PW-space with the reproducing sinc(z-a(n))-kernel functions system.

For the link of the nonharmonic Fourier series theory with its underlying concepts of frames and Riesz bases to the wavelet theory and sampling theorems, which is part of the solution concept of part B, we refer to (ChO), (HoM), (ReH).

(B) A single truly geometric gravity and quantum field theory

After having passed the two milestones, Einstein’s Special Relativity Theory, (BoD1), and Pauli’s spin concept (accompanied by the spin statistics CPT theorem, (StR)), the General Relativity Theory (GRT) and the quantum theory of fields became two „dead end road“ theories towards a common gravity and quantum field theory. The physical waymarking labels directing into those dead end roads may be read as

"towards space-time regions with not constant gravitational potentials governed by a globally constant speed of light", (UnA)

"towards Yang-Mills mass gap".

The waymarker labels of the royal road towards a geometric gravity and quantum field theory may be

towards mathematical concepts of „potential“, „potential operator“, and „potential barrior“ as intrinsic elements of a geometric mathematical model beyond a metric space (*)

towards a Hilbert space based hyperboloid manifold with hyperbolic and conical regions governed by a „half-odd-integer“ & „half-even integer“ spin concept

towards the Lorentz-invariant, CPT theorem supporting weak Maxwell equations model of „proton potentials“ and „electron potentials“ as intrinsic elements of a geometric mathematical model beyond a metric space

:
towards „the understanding of physical units“, (UnA) p. 78, modelled as „potential barrior" constants, (*),(**), (***), (****), (*****)

(*) Einstein quote, (UnA) p. 78: „The principle of the constancy of the speed of light only can be maintained by restricting to space-time regions with a constant gravitational potential.“

(**) The Planck action constant may mark the "potential barrior" between the measurarable action of an electron and the action of a proton, which "is acting" beyond the Planck action constant barrior.

(***) The „potential barrior“ for the validity of the Mach principle determines the fine structure constant and the mass ratio constant of a proton and an electron: Dirac’s large number hypothesis is about the fact that for a hydrogen atom with two masses, a proton and an electron mass, the ratio of corresponding electric and gravitational force, orbiting one another, coincides to the ratio of the size of a proton and the size of the universe (as measured by Hubble), (UnA) p. 150. In the proposed geometric model the hydrogen atom mass is governed by the Mach principle, while the Mach principle is no longer valid for the electron mass, governed by the CPT spin statistics.

(****) The norm quadrat representation of the proposed "potential" definition indicates a representation of the fine structure constant in the form 256/137 ~ (pi*pi) - 8. In (GaB) there is an interesting approach (key words: "Margolus-Levitin theorem", "optimal packaged information in micro quantum world and macro universe") to „decrypt“ the fine structure constant as the borderline multiplication factor between the range of the total information volume size (calculated from the quantum energy densities) of all quantum-electromagnetic effects in the universe (including those in the absense of real electrodynamic fields in a vacuum; Lamb shift) and the range of the total information volume size of all matter in the four dimensional universe (calculated from the matter density of the universe).

(*****) The vacuum is a homogeneous, dielectric medium, where no charge distributions and no external currents exist. It is governed by the dielectric and the permeability constants, which together build the speed of light; the fine structure constant can be interpreted as the ratio of the circulation speed of the electron of a hydrogen atom in its ground state and the speed of light. This puts the spot on the Maxwell equations and the "still missing underlying laws governing the "currents" and "charges" of electromagnetic particles. ...The energetical factors are unknown, which determine the arrangement of electricity in bodies of a given size and charge", (EiA), p. 52:

The Yang-Mills-, Maxwell- and Helmholtz-Equations, the PCT theorem, and simultaneously measurable observables in a Hilbert space framework

The Yang-Mills theory is the generalization of the Maxwell theory of electromagnetism, where the chromo-electromagnetic field itself carries charges. As a classical field theory it has solutions which travel at the speed of light so that its quantum version should describe massless particles (gluons). However, the postulated phenomenon of color confinement permits only bound states of gluons, forming massive particles. This is the mass gap. The physical ("color") confinement challenge is that the phenomenon that "color-charged" particles (such as quarks and gluons) have not been isolated until today. Another challenge of „confinement“ is asymptotic freedom which makes it conceivable that quantum Yang-Mills theory exists without restriction to low energy scales. Therefore, before going for hunting massless bosons, we should either intensify to capture quarks, or revisit the triple, "electron", "neutron", "proton", becoming the only physically observable fermions in a SRT & CPT aligned quantum theory of fields, based on the theory of Hilbert spaces with indefinite inner product, ((DrM), (AzT), (DrM), (VaM)) accompanied with the calculus of variations in a distributional Hilbert scale framework.

The integral form of the Maxwell equations is more closely connected to the physical situation, which is basically the combined Gauss‘ Electric Law and Ampere’s Law, where electromagnetic waves propagate in the interior of a region in R(3) enclosed by a related region boundary. The corresponding two variational representations of the standard „electric“ and „magnetic“ boundary problem is enabled by the Green formulae accompanied with corresponding „natural“ boundary conditions. When applying variational methods, the natural bilinear form of time-harmonic Maxwell equations is not coercive on the whole Sobolev space H(1). One can, however, make it coercive by adding a certain bilinear form on the boundary of the domain (CoM). The extended „electric“ and „magnetic“ (well-posed) boundary value problem is accompanied by the extended Green formulae, replacing the standard normal derivative concept by a „mass element“ and „flux“ concept, which is purely defined on the surface only, omitting the unit vector tangent concept, (PlJ). The proposed physical governing concept is the least action principle, (KnA).

We note that Maxwell equations hold only in regions with smooth parameter functions, modelling conductivity, dielectricity and permeability. Vacuum (i.e. the conductivity is zero) is a homogeneous, dielectric medium, where no charge distributions and no external currents exist. Therefore, the dielectric and the permeability tensors reduce to the dielectric and the permeability constants, which together build the speed of light. In order to consider situations in which a surface separates two media from each other, the constitutive parameters (modelling conductivity, dielectricity and permeability) are no longer continuous (i.e. also not differentiable). The concepts „conductivity“, „dielectricity“ and „permeability“ are proposed to become intrinsic elements of the Hilbert space model, whereby the „transmission boundary conditions“, ((KiA), p. 12) are governed by a least action principle. In scattering theory the solutions live in the unbounded exterior of a bounded domain. In standard theory the behavior of electromoagnetic fields at infinity has to be taken into account (example: Hertz dipole).

The solution of time-harmonic Maxwell equations in a vacuum leads to the Helmholtz equation. The fundamental solution of the Helmholtz equation at the origin is given by spherical wave fronts. The time-dependent magnetic field has the form of the Hertz dipole centered at the origin, (KiA) p. 14. In this example the considered solution functions tends to infinity when absolute(x) tends to infinity. In order to overcome this challenge the wave number k is replaced by the wave number -k. It leads to „outgoing“ and „ingoing“ wave fronts. For the scattering of electromagnetic waves the scattering waves have to be "outgoing" waves. Thus, it is required to exclude the second ones by additional conditions which are called radiation conditions (KiA) p. 15. The concept of „ingoing“ wave fronts (accompanied by (the Sommerfeld or the Silver-Müller) radiation conditions) are proposed to become intrinsic elements of the Hilbert space model, whereby the „transmission boundary conditions“ are governed by a least action principle.

The (mathematically proven) spin-statistics PCT theorem says that "any Lorentz invariant local quantum field theory with a Hermitian Hamiltonian must have PCT (Charge-Parity-Time) symmetry". Mathematically speaking, the PCT theorem states, that the product of the transformations „P“ („Parity transformation“ (resp. a "half integer" and "integer" spin concept), „C“ („Charge conjugation“ (resp. confinement of spin property), „T“ („Time reversal“ (resp. SRT (hyperbolic PDE) scope)), in one order or the other, is always a symmetry in local fields, whether or not the individual factors are. It is one of the only few mathematically proven quantum physical "theorems". The two essential assumptions in proving the spin/statistics relation are "relativity", i.e. the physical laws do not change under Lorentz transformation, and" microcausality", i.e. space-like separated fields either commute or anticommute. It can be made only for relativistic theories with a time direction.

Both quantum theories, the quantum mechanics and the quantum dynamics, are physical systems consisting of measurable variables and observable data; the mathematical model framework is about the same complex number based L(2) Hilbert space for both theories; its elements have wave character, which are built on Fourier series representation based on Hermite polynomials to model observables like location, momentum, energy density and energy radiation. To stablish the states of different observables in the same Hilbert space framework only simultaneously measurable observables may be considered.

Further royal road markings towards a single, geometric gravity and quantum field theory

The central mathematical labelling data for a royal road marking towards a single (truly geometric) gravity and quantum field theory are

- the kinematical energy Hilbert space of the fermions is the standard weak Hilbert space H(1), equipped with the "Dirichlet integral" inner product

- the Hilbert space H(1) allows the split into two complementary spaces, providing a model for the physical concepts of "half-odd-integer" and "even-odd-integer" spins with related repulsive and attractive effects, mathematically governed by Riesz bases coming along with the non-harmonic Fourier series theory

- the Friedrichs extension of the Laplacian operator is a selfadjoint, bounded operator B with domain H(1). Thus, also the operator B induces a decomposition of H(1) into the direct sum of two subspaces, enabling the definition of a „potential“ and a corresponding „grad“ potential operator. Then a potential criterion defines a manifold, which represents a hyperboloid in the Hilbert space H(1) with corresponding hyperbolic and conical regions ((VaM) 11.2)

- the kinematical Hilbert space H(1) is compactly (coarse-grained) embedded into an overall energy Hilbert space H(1/2), whereby the closed complementary subspace of H(1) governs all non-kinematical energies, i.e. the closed sub-space H(1,ortho) replaces all current bosons-type elementary particles

- theoretical physics models are defined as weak (distributional Hilbert scale based) variational (PDE) representations of the considered mechanical system, which is compactly (coarse-grained) embedded into an overall dynamical system. A first proof of concept is given by the Millennium problem of a well-posed initial-boundary value problem of the 3D non-linear, non-stationary Navier -Stokes Equations, where the corresponding variational representation accompanied with an extended H(1/2) energy Hilbert space norm is well-posed

- the physical concept of "potential" is an intrinsic element of the geometric quantum field model, and is no longer an appropriately interpreted physical phenomenon of the considered physical situation; mathematically speaking, the concept of "potential" is an intrinsic element of the geometric Hilbert scale framework, and do not need to be chosen properly as a given functions of the considered PDE

- the "electron potential" (:= electric potential energy/unit charge) in the geometric quantum field (H(1/2) energy related Hilbert space) model corresponds to the electric potential as defined by the weak representation of the Maxwell equations; the hyperboloid manifold in the Hilbert space H(1) with corresponding hyperbolic and conical regions enables a corresponding "proton potential" governed by the related "spin type"; in other words, also the concept of repulsive electrons and attractive positrons are intrinsic parts of the geometric model; the differentiator from a physical perspective is about the fact, that the Planck action constant marks the barrior between the measurarable action of an electron and the action of a proton,which is beyond the Planck action constant

- Fourier transforms do not allow localization in the phase space, leading to the concept of windowed Fourier transforms. From a group theoretical perspective windowed Fourier transforms are identical to the wavelet transforms. The wavelet admissibility condition puts the spot on the Hilbert space H(1/2), (LoA). From a „mathematization“ perspective „wavelet analysis may be considered as a mathematical microscope to look by arbitrary (optics) functions over the real line R on different length scales at the details at position b that are added if one goes from scale „a“ to scale „a-da“ with da>0 but infinitesimal small“, (HoM) 1.2

- the one-dimensional counterpart of the below considered S(3) unit sphere is the unit circle. For the continuous wavelet transform of a function over the unit circle with respect to a wavelet g we recall from (HoM): „Geometrically, the wavelet transform of a function over the circle T is a function over the half-cylinder  R(+) x T. … The Poisson summation formula shows a vanishing constant Fourier term and the positive and negative frequencies do not mix, enabling a corresponding (+/-) split of the L(2) space.  … the wavelet transform over the circle conserves energy. .. The wavelet transform with respect to a progressive, admissible wavelet is an isometry. …. In case where g=h it is now an orthogonal projector on the image of the wavelet transform.

The proposed Hilbert space based model ...

... overcomes the main gap of Dirac‘s quantum theory of radiation, i.e. the small term representing the coupling energy of the atom and the radiation field becomes part of the H(1)-complementary (truly bosons) sub-space of the overall energy Hilbert space H(1/2); the new concept replaces Dirac’s H(-n/2-e)-based point charge model by a H(-1/2)-based quantum element model

... acknowledges the primacy of micro quantum world against the macro (classical field) cosmology world, where the Mach principle governs the gravity of masses and masses govern the variable speed of light, (DeH)

... allows to revisit Einstein's thoughts on ETHER AND THE THEORY OF RELATIVITY in the context of the space-time theory and the kinematics of the special theory of relativity modelled on the Maxwell-Lorentz theory of the electromagnetic field

... acknowledges the Mach principle as a selecting principle to select the appropriate classical cosmology field model out of the few current physical relevant ones, (DeH): the to be selected classical cosmology field equation model may be modelled as the Ritz approximation equation (= orthogonal projection  onto the coarse-grained (energy) Hilbert sub-space H(1) of the overall variational representation in the overall H(1/2) (energy Hilbert) space) of an extended Newton model, accompanied with the Dirichlet integral based inner product, the and the three dimensional unit sphere S(3) based on the field of quaternions in sync with the Lorentz transformation

... aknowledges Bohm's property of a "particle" in case of quantum fluctuation, (BoD), chapter 4, section 9, (SmL).

The GRT describes a mechanical system characterized by the (inert = heavy) mass of the considered „particles“ and their related interacting „gravity force“; the mathematical model framework is about a real number based (purely) metric space. This is about the distance measurment of real number points, which are per definition without any „mass density“, (as long as the field of real numbers is not extended to the field of hyper-real number, i.e. as long as the Archimedian axiom is still valid). For a mechanical system every real-valued function of the location and momentum (real number) coordinates represents an observable of the physical system. The underlying metric space concept (equipped with an (only) "exterior" product of differential forms, because a metric space has no geometric structure at all) accompanied by a global nonlinear stable, Minkowski space, (ChD), is replaced by a H(1/2)-quantum energy Hilbert space concept equipped, where the H(1/2)-inner product is equivalent to a corresponding inner product of differential forms.

The Hilbert space framework supports also the solution to related challenges, e.g. regarding the „first mover“ question (inflation, as a prerequiste) of the „Big Bang“ theory, the symmetrical time arrow of the (hyperbolic) wave (and radiation) equation, governing the light speed and derived from the Maxwell equations by differentiation, no long term stable and well-posed 3D-NSE, no allowed standing (stationary) waves in the Maxwell equation, the mystery of the initial generation of an uplift force in a ideal fluid environment of aircraft wings, i.e. no fluids collisions with the wings surfaces, and a Landau equation based proof of the Landau damping phenomenon.

Some more labelling data towards a single geometric gravity and quantum field model

- the Hilbert space L(2) is compactly embedded into the larger generalized Hilbert space H(-1/2), (with its dual (energy) Hilbert space H(1/2) with respect to the L(2)-norm = L(2) metric)

- the Hilbert space H(-1/2) governs specific variables like (the not measureable) ground state energy

- weak variational (PDE) representations of real valued functions in a Hilbert scale framework, where a „coarse-grained“ (Lebesgue integral based) Hilbert space L(2) governs the modelling requirements of mechanical systems

- the field equations may be represented by the Einstein-Hilbert action functional, which is already a baseline concept in the variational calculus

- the simultaneous measurement of the variables in the H(-1/2) framework is modelled as the orthogonal projections onto the (thermodynamics) statistical („coarse-grained“) Hilbert space L(2), which is compactly embedded into H(-1/2)

- complex numbers play an important role in quantum mechanics; the extension to quantum dynamics needs a somehow richer object than R(3) or C(3) leading to Hamilton's quaternions as a fundamental building block of the universe accompanied by the three dimension unit sphere (UnA1)

- the Hilbert scale structure conserves the mechanical measurements in the standard L(2) Hilbert space framework, while the underlying energy dynamics are governed by the (much larger) orthogonal, closed subpace of L(2) in H(-1/2) with respect to the overall "quantum element" Hilbert space H(-1/2)

- a Hilbert space is THE mathematical role model building geometric spaces, i.e. the proposed „coarse-grained“ Hilbert scale structure is the best possible mathematical option to model the universe, which is nearly all about vaccuum, whereby most of the rest of the vacuum is nearly all about the sophisicated notions of „dark matter“ and „dark energy

- the metric space comes along with the need to choose between three so-called "geometries" (spherical, flat, hyperbolic) in combination with multiple possible, only locally relevant metrices (e.g. Schwarzschild, Robertson-Walker, Gödel), while indefinite inner product spaces provide an all-in-one package, which includes the concepts of a "potential", (independently defined from any coupling constant (!)) and a "potential operator", enabling the definition of a corresponding potential criterion (barrior) defining a manifold, which represents a hyperboloid with underlying hyperbolic and conical regions

- in a 4D-field based Hilbert scale framework the metric space based so-called "geometry" types are replaced by (problem specifically considered) PDE types, which are elliptic (mathematical object behind the naming convention: ellipse), parabolic (mathematical object behind the naming convention: straight (not a parabola)) and hyperbolic (mathematical object behind the naming convention: hyperbole) PDE; only the parabolic (time arrow) and the hyperbolic (time symmetry) PDEs require the concept of "time". The model problems for the three PDE types are (1) the Newton potential equation resp. the Helmholtz equation (elliptic, steady state), (2) the heat equation (parabolic) and (3) the wave (or radiation) equation (hyperbolic). In the context of the concept "wave" we note that "distortion-free progressing wave" (alternatively to "standing waves"), which are key for the theory of transmission of signals, are indeed a central subject in the theory of hyperbolic PDE. Relatively undistored spherical waves relate spherical waves to the problem of transmitting with perfect fidelity signals in all directions. For the related Courant-Hilbert conjecture, putting spherical waves for arbitrary time-like lines in case of two or four variables into a one-to-one relationship to the wave equation, we refer to (CoR) VI. §18. In order to prove this conjecture one might consider the fact that the only possible domain fields of the considered functions are the sets of the 1D real numbers, 2D complex numbers, and the 4D quaternions

- without the parabolic or hyperbolic space-time concept in the purely elliptic world, there is no theoretical model from which the numerical values of the velocity of light and the Planck constant can be derived, as the underlying units „meter“ and „second“ are out of scope, (UnA1) p. 138 ff: Anticipating the Courant-Hilbert conjecture there is the need for an alterative 4D field model, and further anticipating Hamilton’s quaternions. Quarternions are a four dimensional number system enabling a tricky multiplication of complex numbers, leading to a four dimension unit ball with its underlying three-dimensional unit sphere, which is equivalent with rotations in three dimensional space. We note that Plemelj’s concepts of „mass element“ and „flow“ in the context of the Green formulae are intrinsic elements of a unit sphere without the need of a „normal vector“ accompanied with the concept of a „mass density“. With respect to the physical universe we recall the following two quotes, (UnA1) p. 155:

R. Feynman: „Now you can look back and say that Pauli’s spin matrices and operators were nothing but Hamiltion’s quaternions“

W. Hamilton: „Somehow quaternions are a fundamental building block of physical universe“

- a coarse-grained mechanical Hilbert space L(2) embedded into the Hilbert space H(-1/2) allows a re-interpretation of the notion "entropy" in the context of the "discrete" Shannon entropy vs. the log(x)-function based "continuous entropy"; we note that the (still best known) relationship between the notions "volume V", "number of particles N", temperature T", "pressure P", "entropy S" and the related total energy E, as a function of the parameters S, V, N, is given by the total differential dE=TdS-PdV+c*dN

- the coarse-grained mechanical (statistical) Hilbert space L(2) embedded into the overall Hilbert space H(-1/2) puts the spot on the Hawking-Hartle (probability theory related) "Interpretation of "The Wave Function of the Universe"" in (DrW): "the ground state is the amplitude for the Universe to appear from nothing"; ... "Physical probabilities, as exemplified by radioactive decay, start with something, a first situation (particle in space and time) becoming another situation (other particles in space and time). The probability is the chance that the transition from situation one to situation two happens during a certain interval of time, or that a particle is found in a certain volume of space, or something like that". In this context we note that the embeddedness of L(2) into H(-1/2) relates to the embeddedness of the set of rational numbers into the set of real numbers, whereby the countable set Q is a „zero quantity set“ with respect to the L(2) inner product (i.e. the probability to pick rational numbers ot of the set real numbers is zero). We note that the set of the (infinite) solutions of the field equations has the same cardinality as the set of real numbers

- the model supports also Einstein's composition model of radiation (Physikalische Zeitschrift 10 (1909), 185–193), while at the same point in time indicates to revisit the related discourse note with W. Ritz (Physikalische Zeitschrift, 10, (1909), 323-324)

- the extended H(1/2) (energy) Hilbert space framework replacing the Dirichlet integral based inner product space H(1) (derived from the classical Newton potential equation accompanied with Green's identities) leads to a well-posed 3D-non-linear, non-stationary Navier-Stokes boundary-initial value problem accompanied with Plemelj's extensions of Green's identities based on intrinsic surface notions "mass element" and "flux"). At the same time, it omits the Yang-Mills system (the expansion of the Maxwell equations in the context of the SMEP) accompanied with the corresponding (physical) Yang-Mills mass gap problem

- the SMEP (with its underlying separation into the categories fermions (EPs with spin 1/2 (electron, neutrino, quarks) and bosons ("EPs" with spin 0 (Higgs), spin 1 (gluons, W/Z-boson, spin 2 (graviton)) is replaced by a purely fermion based EP model defined in the coarse-grained Hilbert scale pair ((H(0),H(1)), governed by the  complementary closed sub-space with respect to the overall ((H(-1/2),H(1/2)) Hilbert scale framework. As a consequence of the ("color") confinement problem of quarks (the phenomenon that "color-charged" particles (such as quarks and gluons) have not been isolated until today, i.e. they have not been observed until today), the "quark" concept is omitted by the original proton

- fermions are governed the Fermi statistics, whereby two identical fermions (EP with mass) cannot occupy the same quantum state (in a corresponding mathematical world this means that a mathematical „fermion“ object behaves like a rational number). The Fermi oscillator is „a particularly simple system. It is a thing capable only for two levels, zero and „epsilon““, (ScE) p.20. The Fermi oscillator is basically the mathematical model for his famous „spin-concept“. „The so-called „spin statistics theorem“ is one of the few theorems in theoretical physics, which are proven based on very very little assumptions. .. it states that EPs with integer spin are representated by symmetric wave functions, while EPs with half integer spin (k+1/2, k=0,1,2,...) are representated as anti-symmetric wave functions“ (HeW) p. 103. All bosons are governed by the Bose-Einstein statistics, which is concerned with “photon gases”. A characteristic of the Bose-Einstein „photon gases“ statistics is, that the concerned particles do not restrict the number of them that occupy the same (continuous) quantum state . All „photon gas“ particles can be brought into the energetically lowest quantum state (below the critical temperature of “normal gas”), where they show the same “collective” behavior. They occupy a single (continuous) quantum state of zero momentum, while „normal gas“ particles all have finite momentum. The statistical thermodynamics model for "normal gases" is the Planck oscillator; in the proposed model the related Planck-Schrödinger statistics of the n-particle problem starts with k=1, while to case k=0, the ground state energy case, is interpreted as physical condition for an model adequate ground state energy value approximation, from which the reduced Planck action variable can be derived, (ScE)

- Pauli’s spin concept and its related spin statistics theorem is about amathematical object with the 2-value attributes, "half integer" and "integer" multipliers of the reduced Planck action quantum. The "connection" model of those spins is mathematically given by „complex number multiplication“. The proposed fermions model is about the three observable EPs (electron, neutrino, positron) considered in a Hilbert space framework. The underlying field is the three-dimensional unit sphere S(3) enjoying the following properties

i) S(3) is isometric to "rotations in the three dimensional space"

ii) S(3) relates to the multiplication of triplets, Hamilton’s concept of quarternions, (UnA1) p. 148

iii) quaternionic multiplication of a spatiotemporal derivative with „electromagnetic potential“ leads to two terms precisely matching the known expressions for the electric and the magnetic fields of the Maxwell equations, (UnA1) p.152

iv) the governing mathematical concept of the Maxwell equations is the Lorentz transformation, which is a linear transformation mapping space-time onto space-time, preserving the scalar product

- the S(3) model in combination with a complex Lorentz group puts the spot on the famous Spin-Statistics-PCT theorem, (StR), pp. 9, 13: "The PCT theorem is a fundamental symmetry of physical laws. It is the only combination of C, P, and T transformations (see below) that is observed to be an exact symmetry of nature at the fundamental level. In terms of Einstein's SRT, "the CPT theorem says that CPT symmetry holds for all physical phenomena, or more precisely, that any Lorentz invariant local quantum field theory with a Hermitian Hamiltonian must have CPT symmetry""

- regarding general irreducible spinor fields and assumed "wrong" connections of spins with statistics of integer and half-odd integer spins, in which all fields either commute or anti-commute, we refer to the Spin-Statistics Theorem for General Spin, (StR) Theorem 4-10

- wave-mechanical vibrations correspond to the motion of particles of a gas resp. the eigenvalues and eigen-functions of the harmonic (Planck) quantum oscillator modelled in the Hilbert scales L(2)/H(1)). The alternatively proposed energy space (H(1/2) = H(1)+H(1,ortho) indicates to revisit Schrödinger's "purely quantum wave" vision, which is about half-odd integer wave numbers, rather than integer quantum numbers. "The wave point of view in both cases (Bose-Einstein and Fermi-Dirac statistics) or at least in the Bose case (mathematically a simple oscillator of the Planck type) raises another interesting question: we may ask whether we ought not to adopt for the quantum numbers half-odd integers. .... On the other side, if we adopt straightaway, we get into erious trouble, especially on contemplating changes of the volume (e.g. adiabatic compression of a given volume of black body radiation), because in this process the (infinite) zero-point energy seems to change by infinite amounts!" (ScE) p. 50. We emphasis that the proposed model overcomes this challenge, as there is no n-particle problem anymore in the purely continous spectrum world of the considered complementary sub-space of the statistical Hilbert space L(2)

- „Hubble’s observations of a shift to the red in the spectra of the spiral nebulae—the farthest parts of the universe—indicated that they are receding from us with velocities proportional to their distances from us“ (DiP). In the context of the spherical wave conjecture regarding observable the space-time hyperbolic world) Dirac’s „new basis for cosmology“ ((DiP) 1937), suggests „a model of the (physical) universe in which there is a natural velocity (requiring the concept of time) for the matter at any point, varying continuously from one point to a neighbouring point. Referred to a four-dimensional space-time picture, this natural velocity provides us with a preferred time-axis at each point, namely, the time-axis with respect to which the matter in the neighbourhood of the point is at rest. By measuring along this preferred time-axis we get an absolute measure of time, called the epoch.

- An elliptic mathematical „reality“ model of the universe governs two complementary subsets. There is the parabolic/hyperbolic "physical reality world“, (which is a very „small“ (in the sense of a zero quantity set) countable subset of the overall mathematical „reality“ model), accompanied with physical-kinematical notions like „time“, „velocity“, „action“ and e.g. the second law of thermodynamics. Then there is the dominant closed, complementary subset of the "physical reality“ model, accompanied with purely mathematical-not measurable notions like „ground state energy“. In this mathematical reality, (UnA1), concepts like Dirac’s „epoch“ or Penrose’s „cycles of time“ (for an alternative steady state model to describe, what came before the big bang), may be revisited to describe how elementary particles with mass are generated out of the purely mathematical, non-kinematical „world“ and how a kind of "annihilation force" occurs measurable by the second law of thermodynamics. The guiding principle may be, that "time" (resp. only "time duration") as perceived by human consciousness aggregates and reflects the "actions" (accompanied with related "action variables", (HeW)) of observed physical systems, which are detectable and understandable (e.g. the scattering theory based methods or Einstein's composition of radiation model) only by statistical ((L(2)-Hilbert space based) measurement methods. Regarding the prospects success measuring the generation of an elementary particles with mass we note that the sum of countable zero quantity sets is again a zero quantity set

The spectrum of a Hermitian, positive definite operator H in a complex valued Hilbert space H with domain D(A), where its inverse operator is compact, is discrete (measurable/stable). Without the latter property the concept of a continuous spectrum is required (unstable meaurement results). The link back to part A is given by the Berry-Keating conjecture with its mathematical counterpart, the Hilbert-Polya conjecture. It is about the suggestion that the E(n) of the non-trivial zeros ½+iE(n) of the Zeta function are all real, because they are eigenvalues of some Hermitian operator H. Berry’s extensions are that if H is regarded as the Hamiltonian of a quantum-mechanical system then, (BeM)

i) the operator H has classical limits
ii) the classical orbits are all chaotic (unstable)
iii) the classical orbits do not possess time-reversal symmetry.

While the full H(-1/2) based quantum-mechanical system behaves chaotic from an observer perspective (measured in the statistical Hilbert (sub) space L(2)), the underlying complementary sub-systems allow a differentiation between those observable thermostatistical effects and the related, not statistically measurable mathematical model parameters, which are physically governed by physical Nature constants, reflecting the border line to those complementary sub-systems (with purely continuous spectrum).

The proposed circle method above (part A) comes along with a split of the integer domain N (of number theoretical functions) being bijectively mapped onto two sets of integers („odd“ and „even“) on the boundary of the unit circle, both with Snirelman density ½. The two sets may be used to revisit the elementary „particle“ state numbers, n=2n/2 (n=1,2,3, ...) exdended by n=1/2, and Schrödinger’s half integer state numbers n+1/2=(2n+1)/2 (n=0,1,2,...), (corresponding to the levels of the Planck oscillator, see above resp. (ScE) pp. 20, 50)) to re-organize the chaotic model behavior of the current thermodynamics based purely kinematical quantum-mechanical systems.

Further referring to part A we note that the zeta function on the critical line is an element of the sequences Hilbert space l(-1). The Shannon sampling operator is the linear interpolation operator mapping the standard sequences Hilbert space l(2) isomorphically onto the Paley-Wiener space with bandwidth „pi“ (i.e. a signals f represented as the inverse Fourier transform of a L(2) function g can be bijectively mapped to its related sequences f(k) and vice versa). We note that the generalized distributional (polynomial and and exponential decay) Hilbert scales l(a) and l(t,a) allow the definition of corresponding generalized Paley-Wiener scales enabling a (wavelet basis based) convolution integral representation of the zeta function, fulfilling appropriate admissibility conditions for wave functions to support general quantumâmechanical principles.We note that the Fourier transform does not allow localization in the phase space. In order to overcome this handicap D. Gabor introduced the concept of windowed Fourier transforms. From a group theoretical perspective the wavelet concept and the windowed Fourier transform are identical. With respect to the above Hilbert scale framework we note that the admissibility condition defining wavelets (e.g. (LoA)) puts the spot on the proposed H(1/2) (energy) Hilbert space.

From a physical perspective the wavelet transform may be looked upon as a „time-frequency analysis“ with constant relative bandwidth. From a „mathematization“ perspective „wavelet analysis may be considered as a mathematical microscope to look by arbitrary (optics) functions over the real line R on different length scales at the details at position b that are added if one goes from scale „a“ to scale „a-da“ with da>0 but infinitesimal small“, (HoM) 1.2. Technically speaking, „the wavelet transform allows us to unfold a function over the one-dimensional space R into a function over the two-dimensional half-plane H of positions and details (where is which details generated?). … Therefore, the parameter space H of the wavelet analysis may also be called the position-scale half-plane since if g is localized around zero with width „Delta“ then g(b,a) is localized around the position b with width a*Delta“.

The related wavelet duality relationship provides an additional degree of freedom to apply wavelet analysis with appropriately (problem specific) defined wavelets in a Hilbert scale framework where the "microscope observations" of two wavelet (optics) functions g and h can be compared with each other by a "reproducing" ("duality") formula. The (only) prize to be paid is about additional efforts, when re-building the reconstruction wavelet.
