Weak-mixing polygonal billiards

Dynamical Systems 2017-05-04 v1

Abstract

We consider the set of polygons all of whose sides are vertical or horizontal with fixed combinatorics (for example all the figure "L"s). We show that there is a dense G δ\delta subset of such polygons such that for each polygon in this G δ\delta set the billiard flow is weakly-mixing in almost every direction.
