Laplacian spectrum and decay of geodesic flow correlations on hyperbolic surfaces (II)

Abstract

Using PSL(2, R) representation theory, we study the temporal correlations of two observables propagated by the geodesic flow of a hyperbolic surface. If the observables are sufficiently regular, these correlations can be developed asymptotically in an exponentially decreasing manner. Ruelle resonances and their link to eigenfunctions of the Laplacian appear explicitly.
