Ruelle's inequality and Pesin's formula for Anosov geodesic flows in non-compact manifolds

Abstract

In this paper, we prove Ruelle's inequality for the geodesic flow in non-compact manifolds with Anosov geodesic flow and some assumptions on the curvature. In the same way, we obtain Pesin's formula for Anosov geodesic flow in non-compact manifolds with finite volume.
