Ergodicity of a piecewise uniformly hyperbolic map
Mikko Stenlund





Abstract. 
We review the "Sinai-Hopf method" of proving ergodicity for
uniformly hyperbolic maps with singularities, restricting to the case of a
special piecewise linear map on the 2D torus. The talk is based on a 1992
paper of Liverani and Wojtkowski.
