Automorphic Forms on Sl2 (R)

Zusammenfassung An introduction to the analytic theory of automorphic forms! limited to the case of fuchsian groups! but from the point of view of the general theory! ending with an introduction to unitary infinite dimensional representations. The main prerequisites are familiarity with functional analysis and elementary Lie theory. Inhaltsverzeichnis Part I. Basic Material On SL2(R), Discrete Subgroups and the Upper-Half Plane: 1.
