From Maxwell to TGIU_ Informational Curvature and the TEF–CST Unification of Light

\begin{abstract} We show that Maxwell’s equations emerge as the linear limit of the TGIU Informational Curvature Dynamics, where the TGIU Equilibrium Force (TEF) and Curvature State Transform (CST) regulate the propagation of informational curvature (light). In non-flat $\Phi$–$S$ manifolds, electromagnetic fields acquire gravitational–informational correction terms, producing nonlinear self-interactions analogous to nonlinear optics and curved-space electrodynamics. \end{abstract} \section{Introduction} In the Teoria Gravito–Informațională Universală (TGIU), light is modeled as an informational curvature wave regulated by the TGIU Equilibrium Force (TEF) and Curvature State Transform (CST). This framework generalizes classical electromagnetism, showing that Maxwell’s equations arise as the low–curvature limit of a broader informational field dynamics. Here we explicitly demonstrate this reduction and extend it into the nonlinear TEF–CST regime.
