Billiards in generic convex bodies have positive topological entropy
Year: 2024
Type: article
Abstract: We show that there exists a C2 open dense set of convex bodies with smooth boundary whose billiard map exhibits a non-trivial hyperbolic basic set. As a consequence billiards in generic convex bodies have positive topological entropy and exponential growth of the number of periodic orbits.
