Abstract

We prove the Ramanujan-Petersson conjecture for Maass forms of the group SL(2,Z)SL(2,Z), with the help of automorphic distribution theory and pseudodifferential analysis. The first notion is an alternative to classical automorphic function theory, in which the plane takes the place usually ascribed to the hyperbolic half-plane. The Selberg conjecture for Hecke's group Γ0(M)\Gamma_0(M) follows as well.
