Abstract
The authors give asymptotic expansions for t→∞ of the correlation functions of sufficiently regular observables for Z^d extensions of a suitable class of hyperbolic flows, in an abstract setup. The class under study includes the finite horizon periodic Lorentz gas in dimension 2 (i.e., a Sinai billiard) and geodesic flows on abelian covers of compact Riemannian manifolds with negative curvature.
