This week's Mathematical Sciences Department colloquium is given by Dr. Vladimir Dragović, Professor of Mathematics, of the Department of Mathematical Sciences, The University of Texas at Dallas.
We introduce a class of nonconvex billiards with a boundary composed of arcs of con-focal conics which contain reflex angles. We present their basic topological and arithmetic properties. We study their periodic orbits and establish a local Poncelet porism. The connection with interval exchange transformation is established together with the Keane-type conditions for minimality
Coffee will be served in FO 2.610F at 1:30 PM.
