— The Manin conjecture is established for Châtelet surfaces over Q arising as minimal proper smooth models of the surface Y 2 + Z2 = f(X) in AQ, where f ∈ Z[X] is a totally reducible polynomial of… (More)

Let G = SL(2, R) R 2 and Γ = SL(2, Z) Z 2. Building on recent work of Strömbergsson we prove a rate of equidistribution for the orbits of a certain 1-dimensional unipotent flow of Γ\G, which projects… (More)
