Resumen de Local limit theorems on some non unimodular groups

Marc Peigné, Emile Le Page

• Let Gd be the semi-direct product of R*+ and Rd, d = 1 and let us consider the product group Gd,N = Gd x RN, N = 1. For a large class of probability measures µ on Gd,N, one prove that there exists ?(µ) Î ]0,1] such that the sequence of finite measures {(n(N+3)/2 / ?(µ)n) µ*n}n = 1 converges weakly to a non-degenerate measure.
