21-Equation Geometric Unification Framework: Universal Embedding, Complete Proof of the Smooth 4D Poincaré Conjecture, and Empirical Validation from Torsion-Curvature Six-Dimensional Riemann-Cartan Geometry

Xiangdong Zhang

This is Version 29 revised preprint, with three core master equations modified and corrected compared to the earlier draft. We present a complete geometric unification framework built upon six-dimensional Riemann-Cartan geometry, reduced to a closed self-consistent system of 21 t…
