Title:Parabolic flows, renormalization and octagonal billiards
Seminar:Center for Dynamics and Geometry Seminars
Speaker:John Smillie, Cornell
Abstract:
Given a billiard orbit in the square which sides are hit in which order? This question leads to the theory of Sturmian sequences. I will describe joint work with Corinna Ulcigrai where we solve an analogous problem for the regular octagon. If time permits I will explain the connection between our work and the general question of renormalization techniques in parabolic dynamics.
