Title:

Billiards in Rational Prisms

Abstract:

We survey what we know about the dynamics of billiards in
rational prisms, that is, right prisms over rational polygons. We will
discuss how to use beautiful ideas of Furstenberg and Veech to make
connections between mixing properties of billiards in polygons to
ergodic properties of billiards in prisms. There will be lots of
examples, and lots of pictures, and no prior knowledge of ergodic
theory is needed. This is joint work with Nicolas Bedaride, Pat Hooper,
and Pascal Hubert.
