Dynamical zeta functions for Anosov flows via microlocal analysis

Abstract

The purpose of this paper is to give a short microlocal proof of the meromorphic continuation of the Ruelle zeta function for C ∞ Anosov flows. More general results have been recently proved by Giulietti-Liverani-Pollicott [13] but our approach is different and is based on the study of the generator of the flow as a semiclassical differential operator.
