An Upper Bound on Topological Entropy of the Bunimovich Stadium Billiard Map

We show that the topological entropy of the billiard map in a Bunimovich stadium is at most log(3.4908).

Does a billiard orbit determine its (polygonal) table?

We introduce a new equivalence relation on the set of all polygonal billiards. We say that two billiards (or polygons) are order equivalent if each of the billiards has an orbit whose footpoints are dense in the boundary an...

TOPOLOGICALLY WEAKLY MIXING POLYGONAL BILLIARDS

We show that in a typical polygon the billiard map as well as its associated subshift obtained by coding orbits by the sequence of sides they visit are topologically weakly mixing....

Whispering gallery modes in open quantum billiards

The poles of the S matrix and the wave functions of open two-dimensional quantum billiards with convex boundary of different shape are calculated by using the method of complex scaling......

Approximations by Graphs and Emergence of Global Structures

We study approximations of billiard systems by lattice graphs. It is demonstrated that under natural assumptions the graph wave functions approximate solutions of the Schrödinger equation with energy rescaled by the billiard dimensi...

Homotopical rigidity of polygonal billiards

Consider two k-gons P and Q. We say that the billiard flows in P and Q are homotopically equivalent if the set of conjugacy classes in the fundamental group of P, viewed as a punctured sphere, which contain a periodic billiard orbit...
