Resonant Geometry: π as a Field-Dependent Constant

This work introduces a resonant geometric framework where π emerges as a dynamic ratio determined by the local resonance field n(x,y). Using Riemannian notation, the metric is extended to ds²_φ = n²(x,y)(dx² + dy²), linking curvature directly to Δf² field tension.

Fold Metric: A Mathematical Framework for Deriving General Relativity and Quantum Field Theory as Scale-Dependent Limits of Primordial Fold Geometry

This paper presents the Fold Metric framework — a recursive geometric construction proposing that the quantum field was built by successive fold events in which primordial energy, expanding to its propagation limit, decomposed into discrete geometric structures. These structures — folds — are the irreducible units of physical description.

Boundary Compensation Mathematics IV BC-M IV: Finite-Resolution Solution Geometry, Quotient Tubes, and Metric-Entropy Profiles

Let (C, dX) be a declared class of admissible realizations, (D, dD) a data space, Π : C → D an observationmorphism, and d ∈ D an observed datum. At finite data precision, the natural object is not the exact fiberΠ−1(d) but the admissible solution tubeF(δ)d = {x ∈ C : dD(Π(x), d) ≤ δ}.After a preregistered ...
