Emergence of Maxwell Electromagnetism from Toroidal Torsion Geometry.

We demonstrate that classical Maxwell electromagnetism arises as themacroscopic limit of microscopic torsional curvature on compact toroidalvacuum configurations.No (U}(1) gauge principle is postulated.Instead, gauge invariance and Maxwell equations emerge from geometric phasequantization, spin structure, and averaging over compact internal degrees offreedom.The electromagnetic coupling constants are shown to be derived quantitiesdetermined by vacuum stiffness and aperture geometry.
