Title:Billiards in irrational polygons: Overview and recent progress
Seminar:Working Seminar: Dynamics and its Working Tools
Speaker:Anatole Katok and Federico Rodriguez Hertz
Calculation or even estimating complexity of the billiard motion inside a general polygon (even a triangle) is a very challenging problem, see Problem 3. in particular, no explicit subexponential bound is known. We will discuss the background and results giving specific bounds for an open G-delta set of angles (Boshernitzan-Vorobets, unpublished) and a remarkable recent result of Scheglov for a full measure set of of angles.
