„Polygonal Outer Billiards “
Prof. Richard Schwartz , Brown University, USA

Outer billiards, invented by Bernhard Neumann in the late 1950s, is a dynamical system in which a point moves around the outside of a convex shape in the plane, according to certain rules reminiscent of the more familiar ordinary billiards. Jurgen Moser popularized the subject to a certain extent in the 1970s, treating it as a toy model for planetary motion. I will survey the highlights of this subject and then focus on my positive solution of the Moser-Neumann problem, which asks if an outer billiards system can have unbounded orbits. My talk will have lots of computer demos.
