Multiplicity One Theorems and Invariant Distributions

Representation Theory 2009-07-07 v1

Abstract

This is my PhD thesis submitted to the Weizmann Institute of Science. It is based on the papers [AG08c], [AG08d], [AGRS07], [AGS08], [AGS09], [Aiz08] and [SZ08]. This thesis includes an introduction to Gelfand pairs and invariant distributions, a list of tools to work with invariant distributions oriented towards proving Gelfand property and a proof that the pair (GL(n+1,F),GL(n,F)) is a strong Gelfand pair. Namely, we prove that if π\pi is an irreducible admissible smooth representation of GL(n+1,F) and ρ\rho is an irreducible admissible smooth representation of GL(n,F) then dimHomGL(n,F)(π,ρ)1.dim Hom_{GL(n,F)}(\pi,\rho)\leq 1.
