Geometric Unified Interaction Framework in 4D

Abstract This paper presents a geometric framework in strictly four-dimensional space-time that unifies the four fundamental interactions: gravity, electromagnetism, weak, and strong forces. All interactions are described as manifestations of geometric structures: curvature, holonomy, twisting, and knotting of fibre bundles attached to the 4D spacetime manifold. Quantum mechanics emerges naturally from a symplectic structure on the manifold. All field equations and geometric relations are fully derived, with integrals and differential relations explicitly solved wherever possible.
