Billiard flows in nibbled ellipses

Dr. Krzysztof Fraczek talk

Speaker invited by: Prof. Dr. Corinna Ulcigrai

Date: 09.01.19  Time: 13.00 - 14.00  Room: ETH HG G 19.1

I plan to present some basic properties of the billiard flow on nibbled ellipses. The boundary of a nibbled ellipse consist of a chain of elliptic and hyperbolic arcs, all coming from confocal conics. The main aim of the talk is to present some steps and tools in the proof of equidistribution for almost all invariant sets determined by caustics of the billiard.
