Title:Langlands Parameters and Algebraic Varieties
Seminar:GAP Seminar
Speaker:Roger Plymen, Southampton University
Abstract:
The local Langlands conjecture relates arithmetic data, based on a local nonarchimedean fi eld F, with the representation theory of re- ductive groups such as GL(n; F). In this talk, we will show how the extended quotient, an idea from noncommutative geometry, is useful in this context. We will focus on the general linear group GL(n). In this case, Langlands parameters form complex algebraic varieties. We will describe these varieties explicitly. This will be a non-technical talk. Joint work with Anne-Marie Aubert and Paul Baum.
