Title: Uniform bounds for Period integrals and sparse equidistribution

Abstract: Let M be a compact quotient of SL(2,R) and let f be a smooth function of zero average on M. We use spectral methods to get uniform (i.e. independent of spectral gap) bounds for twisted averages of f along long horocycle orbit segments. We apply this to obtain an equidistribution result for sparse subsets of horocycles on M. This is a joint work with J. Tanis.
