Title: Sharp mixing rates for infinite measure preserving systems

Abstract: We will talk about recent results on first and higher order asymptotics of the transfer operator associated with a large class of infinite measure preserving systems (including interval maps with indifferent fixed points). In this sense we provide the optimal scaling/spreading rate (first order theory) along with sharp mixing rates (higher order theory) for a large class of infinite measure preserving systems.
