 Orateur(s) Werner Mueller - Bonn, Titre Spectral theory of automorphic forms and the trace formula Date 05/03/2015 Horaire 17:00 à 18:00 Résume The analytic side of the theory of automorphic forms is concerned with harmonic analysis on a locally symmetric space of finite volume defined by a lattice $\Gamma$ in a semisimple Lie group $G$. One of the main problems is the study of the spectrum of the algebra of invariant differential operators on the corresponding locally symmetric space or, more generally, with the study of the spectral resolution of the right regular representation of $G$ in $L^2(\Gamma\backslash G)$. One of the basic tools is the Arthur-Selberg trace formula. In this talk I will discuss some recent results concerning the asymptotic distribution of automorphic spectra and I will also discuss some problems related to it. Salle Adresse
