Random circular billiards on surfaces of constant curvature: Pseudo integrability and mixing
Abstract
Given a random map (T1, T2, T3, T4, p1, p2, p3, p4), we define a random billiard map on a surface of constant curvature (Euclidean plane, hyperbolic plane, or the sphere). The Liouville measure is invariant for this billiard map. Finally, we show some dynamical properties such as ergodicity in the case of random circular billiards.
