For such flows some of the consequences of the main result are: (a) exponential decay of correlations for H\"older continuous observables with respect to any Gibbs measure; (b) existence of a non-zero analytic continuation of the Ruelle zeta function with a pole at the entropy in a vertical strip containing the entropy in its interior; (c) a Prime Orbit Theorem with an exponentially small error. All these results apply for example to geodesic flows on arbitrary compact Riemann manifolds of negative curvature. %U http://arxiv.org/abs/1301.6855v8
