Chaoticity of generic analytic convex billiards

Dynamical Systems 2026-05-20 v1

Abstract

We show that a generic analytic strongly convex billiard is "maximally chaotic" in the sense that, for every rational number pqQ(0,1)\frac{p}{q} \in \mathbb{Q} \cap (0,1), all intersections between the stable and unstable manifolds of maximizing periodic orbits with rotation number pq\frac{p}{q} are transverse.
