Operations and effects in the Hilbert space formulation of quantum theory

M. Revzen

An hidden variable (hv) theory is a theory that allows globally dispersion free ensembles. We demonstrate that the Phase Space formulation of Quantum Mechanics (QM) is an hv theory with the position q, and momentum p as the hv. Comparing the Phase space and Hilbert space formulations of QM we identify the assumption that led von Neumann to the Hilbert space formulation of QM which, in turn, precludes global dispersion free ensembles within the theory. The assumption, dubbed I, is: "If a physical quantity $\mathbf{A}$ has an operator $\hat{A}$ then $f(\mathbf{A})$ has the operator $f(\hat{A})$". This assumption does not hold within the Phase Space formulation of QM. The hv interpretation of the Phase space formulation provides novel insight into the interrelation between dispersion and non commutativity of position and momentum (operators) within the Hilbert space formulation of QM and mitigates the criticism against von Neumann's no hidden variable theorem by, virtually, the consensus.

Modern theoretical physics is formulated using several highly successful but conceptually distinct mathematical structures. Quantum mechanics is based on Hilbert spaces and linear operators, quantum field theory is formulated through Green functions and propagators, gauge theories rely on fiber bundles and holonomy, while general relativity describes gravitation through differential geometry. Although these mathematical frameworks are deeply interconnected, they are traditionally introduced as independent axiomatic constructions. In this work, we propose a unified mathematical reconstruction framework in which Green functions, Hilbert spaces, gauge transport, and effective geometry emerge from a single primitive transport architecture. The fundamental object is neither a wavefunction nor a spacetime manifold, but an operator-valued reconstruction architecture consisting of directed transport graphs, interaction vertices, closure relations, and recursive consistency maps. Green operators arise naturally as inverse transport operators, Hilbert spaces appear as completions of admissible architectural amplitudes, gauge fields emerge from holonomy of closed transport loops, and effective geometry is reconstructed as the continuum limit of transport consistency. A central Reconstruction Theorem is formulated, establishing that every admissible reconstruction architecture induces Green operators, Hilbert reconstruction spaces, holonomy observables, effective gauge connections, and continuum geometry. As an application, a discrete set of architectural quantum numbers (a,b,c,d) is introduced to characterize propagation, interaction, topology, and recursion. A phenomenological mass reconstruction formula is subsequently derived as an application rather than a fundamental assumption. The proposed framework does not replace established physical theories. Instead, it offers a common mathematical origin from which several of their fundamental structures arise naturally. The work therefore represents a structural reformulation of theoretical physics based on operator-valued transport architectures.

Two-Hilbert space versions of the basic integral-representation formulas for wave and transition operators are derived within the framework of time-independent scattering theory. Multichannel scattering theory for state vectors as well as for statistical operators is presented in a two-Hilbert space formulation to which these formulas become applicable. This formulation stays valid when long-range interactions, for which renormalized wave operators exist, are present.
