Krickeberg mixing for Z-extensions of Gibbs Markov semiflows

Abstract

We obtain Krickeberg mixing for a class of \mathbb Z-extensions of Gibbs Markov semiflows with roof function and displacement function not in L^2, where previous methods fail. This is done via a ‘smooth tail’ estimate for the isomorphic suspension flow.
