Polygonal outer billiards
Abstract: Outer billiards is a basic dynamical system defined
relative to a convex shape in the plane. In many
cases, the system produces beautiful and mysterious
tilings of the plane that are not well understood,
and also the dynamics of these systems are not well
understood. I will survey some results in this subject,
paying particular attention (of course) to my own.
