Abstract:

We develop an abstract framework for obtaining optimal rates of mixing and higher order asymptotics for infinite measure semiflows. Previously, such results were restricted to the situation where there is a first return Poincaré map that is uniformly expanding and Markov. As illustrations of the method, we consider semiflows over non-Markov Pomeau–Manneville intermittent maps with infinite measure, and we also obtain mixing rates for semiflows over Collet–Eckmann maps with nonintegrable roof function.
