1 Rationality Properties of Unipotent Representations
0.1. Let k be an algebraic closure of a finite field Fq with q elements. Let G be a connected simple algebraic group of adjoint type over k with a fixed Fq-rational structure; let F : G −→ G be the corresponding Frobenius map. The fixed point set G is a finite group. Let W be the Weyl group of G. For w ∈ W let Rw be the character of the virtual representation R(w) of G defined in [DL, 1.5]. (Th...
متن کاملUnipotent Automorphic Representations : Conjectures
In these notes, we shall attempt to make sense of the notions of semisimple and unipotent representations in the context of automorphic forms. Our goal is to formulate some conjectures, both local and global, which were originally motivated by the trace formula. Some of these conjectures were stated less generally in lectures [2] at the University of Maryland. The present paper is an update of ...
متن کاملUnipotent Representations and Quantum Induction
In this paper, we construct unipotent representations for the real orthogonal groups and the metaplectic groups in the sense of Vogan.
متن کاملUnipotent Representations as a Categorical Centre
Let G(Fq) be the group of rational points of a split connected reductive group G over the finite field Fq . In this paper we show that the category of representations of G(Fq) which are finite direct sums of unipotent representations in a fixed two-sided cell is equivalent to the centre of a certain monoidal category of sheaves on the flag manifold of G×G. We also consider a version of this for...
