Title:  Tiling billiards and interval exchange transformations

Abstract:   Tiling billiards is a new dynamical system where a beam of light refracts through a planar tiling. It turns out that, for a regular tiling of the plane by congruent triangles, the light trajectories can be described by interval exchange transformations. I will explain this surprising correspondence, and show that we get the Rauzy fractal as a billiard trajectory.
