Abstract

Let GL(n) denote the general linear group over a local nonarchimedean field. For the equivalence classes of irreducible smooth representations of GL(n) admitting nonzero Iwahori fixed vectors, we have the classical Deligne-Langlands parameters. We prove that the Deligne-Langlands parameters have a definite geometric structure: the structure of the extended quotient of a complex torus of dimension n by the symmetric group S_n.

Notes: 1. At the time of publication, the extended quotient was called the Brylinski quotient.

2. We say in the Introduction that this chapter is a "re-interpretation" of [8]. Reference [8] was, however, never published, so this eprint is now the primary source: the book itself is out of print.

3. The main result in this chapter is the precursor of a wide-ranging geometric conjecture, in the representation theory of p-adic groups, developed by Anne-Marie Aubert, Paul Baum and myself in a series of papers from 2007 -- 2011.
