Chaoticity of generic analytic convex billiards

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