We establish an asymptotic expansion of the correlations for the horocycle flow on Abelian covers of compact hyperbolic surfaces. We also prove that the spectra around $0$ of the Casimir operators on any increasing sequence of finite Abelian covers become equidistributed with respect to an absolutely continuous measure. Joint work with D. Ravotti (Wien).
