Classical Entanglement: Parametric Geometry and Non-Parametric Synthesis of Asymptotic Laws

open access: yesAxioms
This review develops a unified geometric framework for synthesizing global asymptotic laws, termed classical entanglement. The central tool is the entanglement operator, a Minkowski–La metric blend that couples asymptotic regimes through an index a>1 ...
