The Unified Evolution Equation (UEE) is constructed as an evolution equation for quantum states that combines reversible phase motion, dissipation due to contact measurement, and resonance transport along a low-dimensional occupation support. Distinguishing geometric occupation from a normalized state, we define a layered Hilbert space using a volume measure and a singular occupation measure. Resonance is described by a skew-adjoint generator $R$ on this space and lifted to the generator R of a unitary conjugation group on states. Contact with an internal pointer is represented by a projective channel and its Poisson evolution. This construction identifies the space on which each term acts, the physical clock, the conserved quantities, and the role of each term in observation. The analysis centers on the sum of three generators on the trace class. In the general case, we assume that the closure of the sum defined on a common dense subspace generates a contraction $C_0$-semigroup, and prove identification with the closure of the natural sum, convergence of the three-factor product, complete positivity, and trace preservation. The closure identification uses dissipativity obtained from the tangent of a contractive approximation family together with a resolvent argument. In concrete realizations, a self-adjoint reversible generator and bounded GKLS dissipation yield a construction of the full semigroup itself. We also establish graph-norm approximation by a common core, $\sigma$-weak continuity of the dual action, and the relation between mild and classical solutions. Extending the construction to evolution on the predual of a specified observable algebra, we give a composition theorem with explicit generation conditions and a finite model with conserved-charge sectors. One-particle transport is lifted to antisymmetric Fock space to define many-body particle number and measurement. Time-dependent bounded perturbations of a fixed unbounded reversible part yield a two-parameter CPTP evolution. We also describe records produced by general instruments and conditions preserving finite moments of unbounded observables. A model consisting of a periodic line and an internal two-level system simultaneously realizes nonzero transport, nonzero dissipation, and a noncommuting internal rotation. We further treat position-dependent interactions and reversible motion containing a second derivative, and calculate local detection probabilities, relaxation, fluxes, and finite-mode approximations. The zero-area property constrains contributions from regular area densities; singular normal currents and entropy coefficients are treated under their respective boundary and representation conditions. The construction thus connects physical inputs to evolution preserving positivity and unit trace, solution regularity, and computable observable predictions.

The Unified Evolution Equation (UEE) provides a common analytical framework that unifies reversible quantum dynamics (unitary evolution), dissipative dynamics of open systems (GKLS), and transport effects induced by boundaries and resonances (zero-area resonance kernels) as a single notion of time evolution of states. The purpose of this paper (UEE_01) is to define the UEE as a mathematically consistent analytical foundation and to establish its well-posedness, including existence, uniqueness, and invariance of states.We formulate the theory by taking the observable algebra as a von Neumann algebra and the state space as its predual, and by characterizing physically admissible time evolutions as preduals of normal, unital, completely positive maps. The UEE is formally expressed as a sum of reversible, dissipative, and resonance-transport generators. Rigorously, solutions are defined in the mild sense as trajectories generated by a strongly continuous completely positive and trace-preserving (CPTP) semigroup.Given the analytical data of the UEE, we construct the reversible, dissipative, and resonance-transport components separately as CPTP group or semigroup evolutions. Using a Chernoff/Trotter-type product formula, we prove that the composite limit evolution exists, forms a CPTP semigroup, and that its generator coincides with the closure of the sum of the individual generators. As a consequence, invariance of the set of normal states and the well-posedness of the UEE are rigorously established.This work provides a solid analytical foundation for the unified GKLS+R representation employed in subsequent papers, ensuring consistency between physical modeling and operator-theoretic dynamics.
Paper XXII of the Six-Throat Directed Geometry program derives the mathematical structure of one-particle quantum mechanics from the directed spinor dynamics established on the regular closed six-throat spacetime. Starting from the conserved curved-spacetime Dirac current, the construction produces a positive and slice-independent inner product and its Hilbert-space completion. The corresponding geometric propagator is unitary and satisfies composition, inverse, and adjoint closure. Real physical observables are represented by self-adjoint operators with real spectra and orthogonal spectral resolutions. The compact global geometry yields an exact periodic commutator algebra, while the standard canonical position-momentum relation is recovered on regular local charts. The Robertson and Schrödinger-Robertson uncertainty relations then follow from the same Hilbert-space structure. The tetrad Clifford algebra generates the intrinsic spin-one-half representation, including the expected spin magnitude, the spinor sign reversal under a full two-pi rotation, and the rotational multiplets obtained by coupling orbital and intrinsic angular momentum. Detector-surface current is promoted from the direct Born-flux construction of Paper XXI to a general positive measurement structure described by a non-projective POVM and the trace probability rule. Density operators, purity, von Neumann entropy, conditional access states, and Kraus dephasing channels arise within the same measurement framework. The positive-energy Dirac branch reduces at low energy to Pauli dynamics and, when the spin-covariant terms commute appropriately, to the Schrödinger Hamiltonian. The same unitary framework yields the Liouville-von Neumann equation, the Heisenberg operator equation, and the Ehrenfest relations in the local directed potential. A forty-three-condition numerical closure audit satisfies all 43 declared conditions across the derived one-particle structure. Representative numerical results include Hilbert-product and unitary residuals at approximately machine precision, exact spin-one-half algebra to numerical precision, POVM completeness at machine precision, low-energy wave-packet infidelity of 3.16 × 10⁻¹⁰ for the stated audit configuration, and Schrödinger-Heisenberg expectation agreement at 5.66 × 10⁻¹⁷. The result is a single geometric chain from conserved spacetime flux to one-particle state space, unitary dynamics, observables, commutators, uncertainty, spin, measurement operators, statistical states, and the low-energy quantum equations. Composite systems, entanglement, exchange symmetry, quantum statistics, and variable-particle-number field theory remain subsequent structural layers and are not claimed as part of the present one-particle closure.
Paper XXIV of the Six-Throat Directed Geometry program extends the fixed-particle-number multipartite quantum theory of the preceding paper to a finite-mode quantum-field architecture. The construction begins from the previously established directed many-particle Hilbert sectors and completes them through a direct sum over particle number, producing a field space in which particle number is spectrally resolved while the directed branch and permutation-statistics labels remain distinct. Normalized insertion and removal between adjacent particle-number sectors generate the symmetric and antisymmetric ladder structures. These operators are then lifted to quantum-field operators on the antiperiodic global modes inherited from the closed Six-Throat spacetime. The resulting finite-mode field algebra is controlled by a reproducing kernel, while the zero-particle sector remains a nonzero Hilbert state. Retaining the directed structure produces two orthogonal zero-particle states that are exchanged under branch reversal. Free field evolution is represented by a unitary geometric propagator preserving antiperiodicity, particle number, and the equal-time field algebra. The first interacting layer is constructed from a self-adjoint local number-changing vertex. It couples adjacent particle-number sectors, produces an exact continuity law in number space, and preserves total Hilbert probability while permitting particle number to vary. Multiple local vertices combine coherently into higher-order interaction networks. At each interaction order, the ordered amplitudes retain an exact directed branch dependence. Starting from the zero-particle sector, branch reversal changes the phase structure of odd particle-number sectors while leaving the corresponding particle-number probabilities equal between the two directed branches. The accompanying reproducibility package verifies 187 declared conditions across eight derivational blocks. The scope established here is the finite-mode directed quantum-field architecture: Fock-space composition, ladder algebra, global field modes, the directed zero-particle doublet, free propagation, particle-number-changing interactions, coherent multi-vertex interference, and higher-order directed interaction networks. Continuum completion, general multi-field species coupling, full-spacetime interaction-density completion, and renormalized continuum observables are outside the scope of the present paper.
This work presents a structural reformulation of quantum dynamics based on a scalar coherence functional defined over a general state space. The framework distinguishes two mathematically natural classes of dynamics generated by such a functional:(i) gradient flows, which monotonically increase coherence and correspond to stabilization or selection processes, and(ii) antisymmetric flows, which conserve coherence and generate reversible dynamics. We show that standard unitary quantum mechanics arises as a special case when the state space is a complex Hilbert space, the coherence functional is chosen as the negative energy expectation, and the antisymmetric structure corresponds to the canonical complex structure. In this setting, the Schrödinger equation follows directly from the formalism, without postulating unitarity as an independent axiom. The framework is extended to open systems using the density-operator formalism and completely positive trace-preserving maps. Under standard assumptions (Markovianity, continuity, and semigroup structure), the reduced dynamics takes the Gorini–Kossakowski–Sudarshan–Lindblad form, with dissipative terms interpreted as coherence-stabilizing dynamics. A supporting lemma demonstrates exponential suppression of off-diagonal density matrix elements under dephasing Lindblad operators. Using the Wigner phase-space representation, we further show that conservative coherence dynamics reduces to classical Liouville transport in the semiclassical regime, with quantum corrections governed by the Moyal bracket expansion. This work does not propose a modification of quantum theory. Rather, it offers a structural reorganization of existing formalisms. All results remain fully compatible with standard quantum mechanics while providing a unified perspective on unitary evolution, decoherence, and the emergence of classical behavior. Related work. A companion technical note, Structural Decomposition of SRG Recursion into Flow, Phase, and Closure (Halldórsson & ChatGPT, 2025, Zenodo), develops a discrete dynamical-systems formulation of SRG-style recursion and connects it explicitly to Lemmas 2.5, 2.7, and 2.9 of the present work.
This paper proves a finite-dimensional collapse-and-obstruction theorem for the relation between Heisenberg observable evolution and Schrödinger state evolution. The starting datum is a completion-locked boundary-channel datum: a boundary Hilbert space, a locked boundary observable algebra, a Heisenberg comparison on boundary observables, and an admissible state-side channel. The basic duality law is the trace pairing Tr[X Φ(ρ)] = Tr[Φ*(X) ρ], restricted, when appropriate, to a locked boundary algebra A∂. The theorem proves that this pairing undergoes Heisenberg–Schrödinger collapse exactly in the full-algebra reversible case: A∂ = B(H∂) and the Heisenberg dual is a ∗-automorphism, equivalently the state-side channel is unitary conjugation. Outside this reversible full-algebra case, the same expectation pairing is a boundary-channel law rather than a unitary full-algebra equivalence. Three rigorous obstructions certify noncollapse relative to the locked boundary datum: a proper boundary algebra is state- and channel-compressive; a nonmultiplicative Heisenberg dual cannot be implemented by unitary conjugation on the full algebra; and a many-to-one bulk/history realization can induce identical boundary laws from inequivalent channels or histories. Thus finite-dimensional closed-system unitary quantum mechanics is identified as the special case in which the boundary algebra is the whole kinematic algebra and the observable-state interface has no quotient, no proper boundary restriction, and no channel-valued loss of reversibility. The theorem has immediate consequences for measurement theory. Nonselective projective measurement is a boundary-channel operation: it fixes the commutative measured algebra while removing off-boundary coherences. Selective measurement is conditioning on a boundary record, not state-uniform retuning of the unconditioned boundary law. Bipartite no-signaling is likewise a fixed-boundary theorem: a remote completely positive trace-preserving channel fixes the local boundary algebra in the Heisenberg picture. Random-unitary symmetry-selection channels and finite rigidity-gap quotient selections supply two realization mechanisms. Their conserved observables are determined by the active commutant, while their low-temperature or equilibrium limits are controlled by explicit channel-norm bounds.

We develop a conditionally closed reconstruction of quantum mechanics from exactly three physical axioms: microscopic ontic definiteness and finite localization, physical reality of the spacetime--vacuum substrate, and persistent causal source--response coupling. Wave functions, Hilbert spaces, complex amplitudes, density operators, the Born rule, commutation relations, Fock spaces, path integrals, completely positive maps, and Markovian dynamics are introduced only as derived mathematical or operational structures, not as additional physical axioms. The construction distinguishes the actual finite carrier and its causal history from the quantum state used to represent preparations, transformations, and measurement probabilities. It derives unitary dynamics from self-adjoint Hamiltonians, formulates spectral observables and probability currents, and states the explicit equilibrium, additivity, noncontextuality, and calibration conditions required for the Born representation. Measurement is described through instruments, pointer dynamics, stable records, weak values, continuous monitoring, diffusive and counting trajectories, and operational error--disturbance relations. Quantum trajectories remain record-conditioned predictive representations rather than automatically ontic paths. Composite systems, identical particles, spin, entanglement entropy, purification, steering, Bell correlations, dense coding, and no-broadcasting are developed on declared tensor-product and symmetry domains. Open-system dynamics are formulated through causal Volterra equations, memory kernels, initial-slip terms, auxiliary-mode realizations, and unitary dilations. Existence, positivity, complete positivity, trace preservation, no-signalling, and energy closure are treated as logically distinct properties. Semiclassical pseudodifferential calculus, controlled path-integral convergence, Ehrenfest-time bounds, semiclassical measures, decoherence, and macroscopic-record stability define the quantum--classical interface. Topological phases, defect-bound states, relativistic wave equations, infrared dressing, and effective quantum-field-theory domains are incorporated with explicit applicability and error conditions. Numerical spectral certification, statistical model comparison, twenty-five benchmark models, theorem-status ledgers, and a complete experimental statistical protocol provide falsification and replication criteria. The resulting framework preserves standard quantum mechanics on its validated domain while isolating finite-core and historical corrections as conditional, quantitatively bounded, and experimentally testable extensions. **Keywords** Quantum foundations; topological quantum mechanics; historical memory; three-axiom reconstruction; Born rule; quantum measurement; weak measurement; quantum trajectories; entanglement; spin and statistics; open quantum systems; Volterra equations; semiclassical limit; quantum topology; numerical certification; experimental falsification.
