This work resolves a foundational tension in Dirac's formulation of relativistic quantum mechanics: momentum appears in two distinct but undifferentiated roles—as a dispersion-locked parameter generating unitary evolution in the relativistic wave equation, and as a free phase variable subject to symplectic flow in the constraint formalism. We demonstrate that this duality reflects an intrinsic Lorentzian structure in energy-momentum space, characterized by the interval dΣ² = dE²/c² − dp². This geometry divides naturally into three sectors: symmetric (dispersion-locked), null (massless, E/|p| = c), and antisymmetric (free-momentum) regimes, each governed by different geometric constraints. Dispersion emerges as the global integral of an exact action one-form, while the (E,p) symplectic structure arises locally as the exterior derivative of the action's inexact form θ_E = E dp. Energy quantization appears as a topological stability condition requiring closed spectral loops to satisfy ∮ E dp = nh, defining "proto-eigenstates" whose Fourier encodings yield standard Hilbert-space eigenstates. We recover both the Bohr spectrum and Dirac fine-structure energies from spectral phase closure, revealing α = e²/(ℏc) as a geometric action-normalization ratio between Maxwell U(1) curvature and Lorentz spinor action—not a coupling parameter from QED perturbation theory. The framework synthesizes unitary flow and symplectic uncertainty into a single bilinear Lorentzian structure, showing quantum states as objective in their symmetric unitary existence but path-dependent in their antisymmetric observed manifestation. This geometric reconstruction bridges Dirac's wave mechanics and constraint formalism through native (E,p) phase space, offering a foundation for quantum theory that treats energy-momentum as primary coordinates rather than conjugate variables derived from spacetime position.

This paper derives the Dirac equation as the logically forced relativistic completion of the de Broglie wave dynamics established in prior work of this series. Starting from the logical foundation that yields Lorentz/Poincaré invariance, we promote the non-relativistic framework (continuous spacetime, Fourier duality, local plane-wave structures, and probability conservation via statistical energy flux) to the relativistic regime. We show that the requirements of exact local relativistic plane-wave structures (with phase gradients satisfying the mass-shell condition pμpμ=m2c2), first-order time evolution (needed for clean probability conservation), and full Lorentz covariance together force the introduction of a specific non-commuting algebraic structure and a multi-component wave function. The Dirac equation emerges as the unique linear differential operator of order at most one in the spacetime derivatives that consistently glues these local structures across smooth backgrounds while preserving a conserved four-current with positive-definite time component. This multi-component structure arises naturally as the minimal algebraic consequence of the constraints, without any separate postulate for intrinsic angular momentum. In exact analogy with the emergence of the finite invariant causal speed in special relativity, the Dirac dynamics is revealed not as an ad-hoc linearization of the Klein--Gordon equation, but as the mathematically inevitable description of indivisible particles in continuous relativistic spacetime. The derivation thereby completes the single-particle sector of the series, demonstrating that core structures of relativistic quantum mechanics flow deductively from a small number of deep, nearly tautological commitments.
In this work, we introduce a novel framework for quantum dynamics based on a second-order evolution equation, ∂2/∂t2∣Ψ⟩=K∣Ψ⟩ , with K=i(αD+βV) , where the operators D and V satisfy the Heisenberg algebra [D,V]=dI in d -dimensional space. Unlike conventional quantum mechanics governed by the first-order Schrödinger equation, this formulation emerges from a unified dynamical structure rooted in phase-space symmetry, naturally accommodating non-Hermitian interactions while preserving unitary evolution through the introduction of an η -inner product and a dual-state mapping. We demonstrate that this theory shares an SL(2,R) symmetry with the standard quantum formalism, revealing that both the Schrödinger and our second-order dynamics arise as distinct realizations within the same symplectic framework — the former as a quadratic generator (energy conservation), the latter as a linear generator (driving-dissipation balance). Extending the theory to four dimensions via Dirac matrices yields a covariant, spinor-valued wave equation whose stationary solutions carry instanton topological charge, π3(S3)=Z , thereby unifying the topological structures from one to four spatial dimensions under the homotopy classification πd−1(Sd−1)=Z . This approach not only generalizes non-Hermitian quantum mechanics beyond PT -symmetric potentials but also establishes a direct bridge between quantum dynamics, symplectic geometry, and topological field theory.
Description This work investigates the mathematical and structural relationship between Schrödinger wave mechanics, Dirac’s relativistic quantum theory, charge conjugation, duality, opposition, equilibrium, and the concept of transduction developed within the framework of Primitive Architecture. The analysis begins with the wave function and the Schrödinger equation and proceeds to the relativistic structure introduced by Dirac. Particular attention is given to the pair of relativistic energy branches E±(p)=±p2c2+m2c4,E_{\pm}(p)=\pm\sqrt{p^2c^2+m^2c^4}, and to the mathematical structure of opposition represented by the transformation d↦−d.d\mapsto-d. The work formalizes this opposition as an involution, C2=I,C^2=I, and establishes the centered representation X=x0+d,X′=x0−d,X=x_0+d,\qquad X'=x_0-d, with x0=X+X′2,d=X−X′2.x_0=\frac{X+X'}{2}, \qquad d=\frac{X-X'}{2}. Within the normalized architectural representation, the structural center is x0=12,x_0=\frac12, with the corresponding involution C(x)=1−x.C(x)=1-x. The work distinguishes the abstract mathematical structure of duality from its specific physical realizations. In particular, it distinguishes the transformation of the sign of energy in the Dirac spectrum from charge conjugation and does not identify these operations as physically identical. Instead, it investigates their common formal structure as transformations between complementary configurations. The analysis also examines the Clifford-algebraic structure of the Dirac formalism through the decomposition AB=12{A,B}+12[A,B],AB= \frac12\{A,B\} + \frac12[A,B], where the anticommutator represents the symmetric component and the commutator represents the antisymmetric component. The corresponding Dirac relation {γμ,γν}=2ημνI\{\gamma^\mu,\gamma^\nu\} = 2\eta^{\mu\nu}I is considered in relation to the architectural distinction between equilibrium and opposition. The work then develops the concept of Relational Conjugation as a structural operation satisfying C(X)=X′,C(X′)=X,C2=I,C(X)=X', \qquad C(X')=X, \qquad C^2=I, together with the preservation of an appropriate invariant, I(C(X))=I(X).I(C(X))=I(X). This produces the closed relation X→C(X)→C2(X)=X.X\rightarrow C(X)\rightarrow C^2(X)=X. The same structure is examined in relation to Spiral Geometry, rs(t,θ)=A(t)esθ,s∈{−1,+1},r_s(t,\theta)=A(t)e^{s\theta}, \qquad s\in\{-1,+1\}, for which rsr−s=A(t)2.r_s r_{-s}=A(t)^2. The work therefore establishes a formal correspondence between opposition, centered duality, conjugation, invariance, transduction, and closure while maintaining the distinction between established physical theory and the architectural layer proposed in this research. A mathematical-computational auditing framework is also formulated. For a configuration XiX_i, its conjugate Xi′=C(Xi)X_i'=C(X_i), and an invariant II, the framework evaluates involution, invariant preservation, centered symmetry, and a coherence metric: Φi=w1∣C2(Xi)−Xi∣+w2∣I(Xi′)−I(Xi)∣+w3∣Xi+Xi′−2X0∣.\Phi_i = w_1|C^2(X_i)-X_i| + w_2|I(X_i')-I(X_i)| + w_3|X_i+X_i'-2X_0|. Exact structural compatibility corresponds to Φi=0.\Phi_i=0. The resulting framework is organized according to the sequence: Relation → Opposition → Equilibrium → Transformation → Invariant → Closure. Within the broader Primitive Architecture research program, this sequence is connected to the more general processes of movement, latency, transduction, form, memory, resonance, and cycle. The contribution of this work is not the creation of the Schrödinger equation, Dirac equation, Clifford algebra, relativistic energy-momentum relation, or the established physical theory of particles and antiparticles. These are treated as established mathematical and physical foundations. The proposed contribution consists in organizing selected structures from these theories within the conceptual and mathematical framework of Primitive Architecture, particularly through involution, center-deviation decomposition, relational conjugation, invariant preservation, transductive transformation, and structural closure. The work therefore presents Primitive Architecture as a formal organizational framework for examining duality and conjugation across different mathematical representations while preserving the distinction between mathematical construction, physical formalism, computational auditing, and theoretical interpretation.
We extend the framework of Unified Quantum Mechanics (UQM) to the relativistic domain by formulating the Dirac equation entirely in terms of real-valued fields. In this approach, the complex imaginary unit i is systematically replaced by the temporal Hilbert transform operator Ht, which satisfies the anti-involution property Ht2=−I and acts as a dimensionless isometric operator. The resulting theory is expressed as a coupled system of real-valued equations for a primary field ψ and its Hilbert-transformed partner ϕ=Ht[ψ], whose evolution is governed exclusively by local differential operators. We demonstrate that all essential algebraic and symmetry structures of relativistic quantum mechanics are preserved within this real-valued formulation. In particular, the full Clifford algebra of the Dirac matrices, Lorentz covariance, and the relativistic energy-momentum relation are recovered exactly. A rigorous isomorphism with the conventional complex Dirac equation is established via the analytic signal representation ψa=ψ−iϕ, under which the standard U(1) gauge symmetry emerges naturally as a global SO(2) rotation in the real field space. The resulting formulation is therefore operationally and predictively equivalent to the standard complex theory. The conserved scalar density ρ=ψ†ψ+ϕ†ϕ=∣ψa∣2 is shown to arise as the squared envelope (intensity) of a real physical field and admits a direct interpretation as a local field intensity with well-defined physical dimensions. Probability conservation is recovered through the continuity equation, while normalization in standard quantum mechanics is reinterpreted as a rescaling by the conserved total field. Stability of matter, expressed as energy positivity, is shown to restrict the physical solution space to analytic signals, enforcing a Hilbert-pair structure and eliminating independent complex degrees of freedom. This work demonstrates that the complex structure of relativistic quantum mechanics is not fundamental but emerges from the analytically constrained dynamics of real-valued fields, providing a unified and physically transparent foundation for the Dirac theory.
This paper proposes and systematically constructs a novel formulation of quantum mechanics based on complete sets of dual variables and integral operators. Its core postulate elevates the operators of time,spatial position, and phase angle to an equal footing with those of energy, momentum, and action, forming three fundamental dual pairs. Building on this, we define the integral operators ˆT and ˆX for time and space, and derive as a first principle the Quantum Action Balance Equation (QABE)—an integral equation with the action phase eiScl/ℏ as its kernel. We rigorously demonstrate that the Schr¨odinger equation, Dirac equation, and Heisenberg equation naturally emerge as specific limits or corollaries of the QABE under local approximations or expectation value evolution. Furthermore, the Feynman path integral emerges as the direct iterative solution form of this integral equation. We clarify that the quantization of action, phase, and spacetime is not an additional hypothesis but an inevitable mathematical consequence of solving this continuous dynamical framework under inherent algebraic constraints (such as phase compactness) or external physical boundary conditions (such as spacetime periodicity), achieving a conceptual unification for the origin of quantization. Importantly, the inherent non-locality of this integral formulation provides an intrinsic mechanism to circumvent ultraviolet divergences in quantum field theory. This work aims to provide a deeper unified foundation for the different formulations of quantum mechanics and to open new conceptual pathways for bridging quantum theory and gravity
Starting from three fundamental duality relations (time-energy, space-momentum, angle-angular momentum), we establish an integral equation of quantum action and its dual counterpart. This integral equation directly links the evolution of the wave function to the accumulated action of spacetime and rotational degrees of freedom, forming a unified framework for quantum theory. Through semiclassical expansion, local approximation, and relativistic covariance, we rigorously derive the Schr\"odinger equation, Klein-Gordon equation, Dirac equation, Heisenberg equation, Schwinger-Dyson equation, Feynman path integral, Yang-Mills equations, Einstein field equations, and the Friedmann and Schwarzschild solutions. The framework also yields the kinematic effects of special relativity (time dilation, length contraction, mass-energy equivalence) as consequences of the duality structure. Moreover, the nonlocal kernel in the integral equation gives an exponential damping factor in momentum space, providing an intrinsic regularization mechanism for ultraviolet divergences. We extend the framework to quantum electrodynamics (QED), quantum chromodynamics (QCD), the electroweak theory, the full Standard Model, and quantum gravity, obtaining dual formulations for each. From the integral equation and its dual, we automatically derive quantization conditions for energy, momentum, angular momentum, and their duals, and propose experimental schemes to observe these discrete effects. All derivations are complete and rigorous, based on the same integral equation, providing a possible answer to Dirac's criticism that "quantum electrodynamics lacks a fundamental equation" and opening a new path toward a unified theory.
