Deriving a Persistence-Weighted Path Integral

Abstract

This paper derives a persistence-weighted path integral from first principles of coherent comparison under composed admissible variation. Rather than postulating probabilistic, geometric, or dynamical structure, the analysis asks which bookkeeping devices are unavoidable if comparison is to remain well defined when admissible variations are recomposed, refined, or reordered. Starting from minimal operational requirements—discernibility, admissible variation, and persistence—the paper shows that path dependence, accumulated loss, stationarity, and quadratic stability classification are structurally forced. An accumulated loss functional emerges as the minimal additive bookkeeping required for coherence, and persistence weighting arises as a monotone representation of the induced ordering on admissible paths. Under additional stability requirements, the exponential weighting appears as a canonical representative compatible with arbitrary recomposition. Second-order variation around persistence-stationary paths yields a quadratic stability form, which can be repackaged as a curvature operator acting on admissible perturbations. Spectral structure then appears as a classification of persistence-relevant deviations, without presupposing geometry, dynamics, or operator postulates. Familiar formalisms—path integrals, entropy-weighted amplitudes, and spectral descriptions—arise only as restricted realizations once further admissibility, locality, and representational constraints are imposed. The entropy-weighted Feynman path integral is recovered explicitly as such a downstream specialization, with all additional assumptions labeled. The result is not a constructive physical model but a boundary-forming derivation: it fixes which structures are forced by coherence of comparison and which questions are deferred to later, more constrained analyses. The paper provides a foundational anchor for subsequent applications that treat persistence-weighted amplitudes and curvature operators as fixed inputs rather than postulates.

Eigenphysics from Persistence - Spectral Structure as a Consequence of Discernibility

David Sigtermans

A structural derivation of spectral structure and quantization is obtained from minimal requirements on discernibility and persistence under variation. Rather than postulating quantum degrees of freedom, operators, or Hilbert space, the analysis identifies which assumptions are required for eigenstructure to arise as a consequence of stability under irreversible loss. Building on prior results establishing accumulated loss, path dependence, and curvature as necessary consequences of persistence, the paper introduces a clear admissibility ledger. Under explicit conditions—ordered variation, local loss density, and a quadratic stability regime—the second variation of accumulated loss defines a curvature operator that classifies admissible deviations by their susceptibility to persistence loss. Eigenmodes emerge as stability classes selected by persistence filtering, not as fundamental postulates. Discrete spectra appear only when admissibility conditions enforce effective compactness. Additional restrictions concerning closed continuations and phase-valued transport lead to a closure condition under repeated traversal, reproducing Bohr-type quantization as a conditional consequence rather than an axiom. Global spectral weights and regularization are introduced solely as technical bookkeeping devices when persistence comparison is extended to families of modes. The framework deliberately separates structural derivation from physical interpretation. Hilbert space structure, probabilistic interpretation, and standard quantum dynamics arise only under further assumptions and are not required for spectral stability itself. Standard quantum mechanics is recovered as a specialization of the general framework under additional linearity, normalization, and interpretive assumptions. The paper isolates the minimal structural content underlying eigenstructure and quantization, making explicit which assumptions are responsible for each step. It stops short of system-specific applications, but the entropy-weighted variational object derived here serves as the foundation for predictive extensions developed in companion works, including corrections to tunneling behavior, interference suppression, and collapse-like phenomena emerging from resolution instability.

Tunneling and Bound States from Persistence-Weighted Calculus

David Sigtermans

This paper analyzes quantum tunneling and bound states as empirical stress tests for a persistence-based comparison framework. Rather than postulating wave mechanics or operator dynamics, the analysis takes as fixed a small set of structural ingredients: admissible variation, accumulated loss under recomposed change, and a persistence requirement selecting stable continuations. Within this framework, persistence-weighted path amplitudes and an associated quadratic stability operator arise as derived objects. The paper examines what is forced when these objects are applied to barrier penetration and confinement, and which standard quantum-mechanical results are recovered only as correspondence limits under additional conditions. Tunneling is treated as a local suppression problem, while bound states are analyzed in terms of closure and stability rather than operator postulates. Explicit worked examples demonstrate how WKB exponents and discrete spectra emerge in entropy-flat limits, and how controlled deviations arise when admissibility or curvature conditions are relaxed. No new principles are introduced. The results isolate the structural footing of familiar semiclassical constructions and delineate a clear window of falsifiability for persistence-based comparison beyond standard wave-mechanical representations.

Stability, Boundary Observability, and Emergent Probability in Deterministic Systems

William Andrew Lawrence

This paper is Part II of The Pre-Emergence Origin of Probability trilogy. Part I develops the structural requirements for finite recurrent stability before spacetime. Part II asks when persistent boundary-readable structure can support numerical probability. Part III examines what probability-status remains after boundary loss, before numerical weighting, and under what narrower conditions Born-form weighting may follow. The paper analyzes how probability-measure status may arise within a closed deterministic description rather than being assumed as a primitive numerical rule. A closed description cannot appeal to an external observer, hidden weighting convention, retained label, post-outcome selection, or independently supplied probability measure to explain its own probability assignments. Numerical probability must instead be supported by structures and relations admitted within the described system. The analysis begins with the requirements for persistent structured identity. Persistent identity is treated as recoverable cross-state relational distinction rather than exact sameness, repeated naming, scalar aggregation, or externally preserved memory. Within the tested structural registry, persistent refinable identity requires ordered dependence, a sufficient stabilization architecture, distributed relational structure, recurrence, bounded recoverability, and noncollapse of the distinctions being preserved. Bounded recurrent relational correction is classified as weak oscillatory form in a deliberately structural sense. The classification does not establish a physical wave, sinusoidal motion, exact periodicity, frequency, propagation, dynamics, mechanism operation, or physical carrier. It identifies a recurrent recoverability architecture that a later realization would have to preserve. The paper then develops the transition from persistent structure to boundary observability. Representation-sensitive bulk descriptions may depend on phase origin, refinement history, decomposition, internal labels, subpart identity, or other distinctions that do not survive admissible boundary readout. Under admissible-observable indistinguishability, boundary-readable observables factor through an emergence-boundary quotient that preserves only the distinctions carried by the admitted observable family and surviving the declared transport relation. The boundary quotient does not itself provide probability. It supplies a local architecture of boundary-readable alternatives and permits the admission of candidate nonnegative contribution scalars. Neither the alternative carrier nor a candidate scalar establishes scalar uniqueness, scalar closure, additivity, measure realization, normalization, or probability interpretation. Numerical probability-measure status becomes available only under a narrower cumulative condition package. The package requires an exact finite carrier, a finite positive event measure, a normalized scalar component on the same carrier, exact scalar-measure compatibility, one-scalar factorization of every admitted weight-bearing map, exclusion of independent weight-bearing invariants, pre-outcome assignment, absence of an external weighting source, and a declared scalar-only predictive regime. Additivity, commensurability, regularity, positive scale, finite nonzero total, and normalization remain separately controlled conditions within that route. Under those conditions, normalized scalar weights may receive conditional probability-measure status inside the declared local regime. This is not an unconditional derivation of probability from determinism. The result does not establish unrestricted probability, universal scalar representation, a global probability law, objective chance, stochastic dynamics, collapse, measurement theory, physical realization, or a final physical theory. Within the trilogy, Part II therefore supplies the middle structural layer: persistent recurrent structuretoboundary-readable alternativestocandidate scalar contenttoconditional numerical probability-measure status. Part III begins from a different question. It examines what remains when a boundary-readable description loses the ability to guarantee which admissible alternative obtains, before any numerical scalarization is supplied. Part II provides the scalar, measure, normalization, compatibility, and realization-burden architecture inherited by that later analysis, but it does not pre-establish the boundary-loss results of Part III. ### Revision note This revision is a substantial reconstruction and trilogy integration rather than a minor editorial update. The derivational architecture, definitions, condition packages, failure boundaries, dependency order, and claim-scope controls have been revised throughout. The manuscript has also been rewritten in new prose to present the argument as Part II of The Pre-Emergence Origin of Probability trilogy. Major changes include a clearer separation of persistent identity, ordered dependence, stabilization, distributed relational recurrence, weak oscillatory form, boundary observability, candidate scalar status, scalar closure, measure realization, normalization, and conditional probability-measure status. The emergence-boundary quotient and transport-survival architecture have been clarified, and the numerical-probability result has been narrowed to an expressly declared scalar-only predictive regime satisfying the complete carrier, measure, compatibility, factorization, pre-outcome, and independent-invariant exclusion conditions. The revision also strengthens the distinction between candidate weights, normalized weights, conditional measures, and probability interpretation. It adds more precise failure localization, preserves the distinction between conditioned failure and universal impossibility, and expands the realization-burden architecture separating mechanism satisfaction, physical scalar selection, boundary enforcement, branch generation, refinement implementation, physical realization, theory-specific realization, empirical validation, and final physical-theory status. The paper is now explicitly positioned between Part I, which establishes the structural requirements for finite recurrent stability before spacetime, and Part III, which develops boundary-unresolved and pre-numerical probability-status after recoverability loss. The central research program remains mechanism-neutral. No physical mechanism, collapse process, specific realization theory, unrestricted probability law, or empirical validation is claimed.

Syntactic Structure, Quantum Weights

Kentaro Imafuku

Why do local actions and exponential Euclidean weights arise so universally in classical, statistical, and quantum theories? We offer a structural explanation from minimal constraints on finite descriptions of admissible histories. Assume that histories admit finite, self-delimiting (prefix-free) generative codes that can be decoded sequentially in a single forward pass. These purely syntactic requirements define a minimal descriptive cost, interpretable as a smoothed minimal program length, that is additive over local segments. First, any continuous local additive cost whose stationary sector coincides with the empirically identified classical variational sector is forced into a unique Euler--Lagrange equivalence class. Hence the universal form of an action is fixed by descriptional structure alone, while the specific microscopic Lagrangian and couplings remain system-dependent semantic input. Second, independently of microscopic stochasticity, finite prefix-free languages exhibit exponential redundancy: many distinct programs encode the same coarse history, and this redundancy induces a universal exponential multiplicity weight on histories. Requiring this weight to be real and bounded below selects a real Euclidean representative for stable local bosonic systems, yielding the standard Euclidean path-integral form. When Osterwalder--Schrader reflection positivity holds, the Euclidean measure reconstructs a unitary Lorentzian amplitude.

Foundations of Coherence Algebra

Flip Boer

The mathematical structure of quantum theory is usually postulated rather than explained—Hilbert spaces, operators, and probabilistic structure—without explaining why this arena should exist in the first place. In this work we address a more primitive question: starting from the absence of any prior structure, what conditions must be satisfied for coherent persistence to be possible at all? We begin from a state of zero determination (the Void), understood not as physical emptiness but as the absence of admissibility constraints. From this starting point, we show that the possibility of persistence forces a minimal triadic structure consisting of reference, transformation, and return. This structure enables self-verification without external supervision and distinguishes genuine continuity from accidental resemblance. The requirement of self-verifying persistence forces deviation to be representable quantitatively and to compose across histories. This necessity leads uniquely to a linear vector space structure. Stability further imposes a knife-edge viability condition: identity-preserving and identity-violating contributions must equalize at closure. From this condition, an inner product and norm are forced, yielding Hilbert space geometry and operator representations as consequences of viability rather than axioms. Within this framework, familiar features of quantum kinematics—such as uncertainty, unitary evolution, and probabilistic weighting—arise as structural necessities rather than postulated rules. The present work establishes the kinematic foundations of coherence, deriving the mathematical arena of quantum theory from the requirement that something persist at all. Applications to mass relations, symmetry, temporal ordering, and composite systems are developed separately.Version 1.0. This preprint establishes the structural foundations of Coherence Algebra and derives Hilbert space from self-verification and persistence.

Physical Law From Structural Coherence

Flip Boer

Modern physics relies on several highly successful mathematical frameworks — quantum theory, gauge theory, general relativity, and thermodynamics. These theories describe nature extremely well, yet their mathematical forms are usually introduced through independent postulates. This work asks a prior question: why do these mathematical structures appear at all? The framework developed here begins from two minimal structural requirements for persistence:coherent return (self-consistency under transformation) and triadic closure (the minimal structure required for such verification). Within clearly stated domain restrictions — independent composability, smooth relational locality, and finite resolution — these postulates impose strong constraints on how physical systems can be represented. From these structural constraints, several familiar elements of modern physics arise as minimal admissible forms: • complex Hilbert space and unitary quantum evolution• quadratic weighting (Born rule)• relational geometry and Einstein-type gravitational response• irreversible temporal ordering from non-invertible return• entropy and the Second Law from indistinguishability growth• compact unitary gauge structure The framework does not attempt to predict parameter values or replace existing physical theories. Instead, it explains why the mathematical forms used by those theories are structurally admissible once coherent persistence under finite resolution is required. As a numerical application, the Koide relation for charged-lepton masses is shown to arise as a geometric consequence of triadic equilibrium in quadratic mass-amplitude space, conditional on the charged-lepton family realizing a coherent triadic structure. The result is a structural program for physics: rather than proposing new dynamical laws, it constrains the mathematical forms that viable physical laws may take.
