## Unique ergodicity of geodesic flow in an infinite translation surface Rafi, Kasra | CIRM H

Multi angle

Research talks;Dynamical Systems and Ordinary Differential Equations

The behaviour of infinite translation surfaces is, in many regards, very different from the finite case. For example, the geodesic flow is often not recurrent or is not even defined for infinite time in a generic direction.
However, we show that if one focuses on a class of infinite translation surfaces that exclude the obvious counter-examples, one can adapted the proof of Kerckhoff, Masur, and Smillie and show that the geodesic flow is uniquely ergodic in almost every direction. We call this class of surface essentially finite.
