Speaker: Ilya Vinogradov (Bristol, UK) Title: Effective Ratner Theorem for ASL(2, R) and the gaps of the sequence \sqrt n modulo 1 Abstract: Let G=SL(2,\R)\ltimes R^2 and Gamma=SL(2,Z)\ltimes Z^2. Building on recent work of Strombergsson we prove a rate of equidistribution for the orbits of a certain 1-dimensional unipotent flow of Gamma\G, which projects to a closed horocycle in the […]
