Title: Mixing for dynamical systems with infinite measure
Abstract: We describe results on mixing for a large class of dynamical systems (both discrete and continuous time) preserving an infinite ergodic invariant measure. The method is based on operator renewal theory and an extension of the renewal-theoretic techniques of Garsia & Lamperti from probability theory.
This is joint work with Dalia Terhesiu.
