GEOMETRIC ORIGIN OF BPS STATES AND THE UNIFICATION OF FUNDAMENTAL PHYSICS: FROM THE LOGICAL IMAGINARY UNIT TO OPTIMAL LATTICES, THE HODGE CONJECTURE, AND TOPOLOGICAL SOLITONS

We present a complete unification of fundamental physics and deep mathematics based on a single principle: the logical imaginary unit I2 C = −Id arising from the minimization of logical deviation in cycles of interpretations [1]. Building on the rigorous geometric foundation established in that work, we develop a variational principle that identifies torsion with Yang-Mills gauge fields as the unique minimizer of a geometric action. This principle, together with the splitting ˜X ∼= Ei × K where Ei is the squareelliptic curve and K has holonomy SU(3) × SU(2) × U(1), yields:• The selection of natural candidates for an optimal 4D lattice for spacetime discretization, with profound implications for lattice QCD;• A geometric realization of the integrality conditions underlying the Hodge conjecture;• A rigorous derivation of the Bogomol’nyi equations for BPS-saturated states;• The explicit construction of the ’t Hooft–Polyakov monopole within our geometry;• Quantum corrections to BPS masses expressed through the Epstein zeta function Zi(1/2), computed in a controlled adiabatic approximation;• The unification of all topological solitons (monopoles, instantons, vortices) as different projections of the same geometric structure.This work demonstrates that the logical principle I2C = −Id is not merely the origin of quantum mechanics and the Standard Model, but a unifying source connecting fundamental physics with three of the deepest conjectures in mathematics: the Riemannhypothesis, the Hodge conjecture, and the Birch–Swinnerton-Dyer conjecture. The natural lattice candidates suggested by our geometry provide ageometric foundation for lattice QCD and point toward optimal discretizations of space-time for numerical simulations.
