Generic Character Sheaves on Disconnected Groups and Character Values
We relate a generic character sheaf on a disconnected reductive group with a character of the rational points of the group over a finite field extending a known result in the connected case.
متن کاملCharacter Sheaves on Disconnected Groups
Throughout this paper, G denotes a fixed, not necessarily connected, reductive algebraic group over an algebraically closed field k with a fixed connected component D which generates G. This paper is a part of a series [L9] which attempts to develop a theory of character sheaves on D. Our main result here is the classification of ”unipotent” character sheaves on D (under a mild assumption on th...

In this paper we define and study generalized Green functions for possibly disconnected groups.
متن کاملCharacter Sheaves on Disconnected Groups, X
We classify the unipotent character sheaves on a fixed connected component of a reductive algebraic group under a mild condition on the characteristic of the ground field.

We prove orthogonality formulas for the characteristic functions of certain complexes on a connected component of a reductive group.
