Character Sheaves on Disconnected Groups, Iv
We construct a basis for the space of invariant functions on the rational points of a possibly disconnected reductive group over a finite field, coming from intersection cohomology
متن کامل3 Character Sheaves on Disconnected Groups , Iv
Throughout this paper, G denotes a fixed. not necessarily connected, reductive algebraic group over an algebraically closed field k. This paper is a part of a series (beginning with [L10], [L11], [L12]) which attempts to develop a theory of character sheaves on G. The numbering of the sections and references continues that of the earlier Parts. Assume that k is an algebraic closure of a finite ...

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.
