Character sheaves on disconnected groups, I

Author:

Lusztig G.

Abstract

In this paper we begin the study of character sheaves on a not necessarily connected reductive algebraic group G G . One of the themes of this paper is the construction of a decomposition of G G into finitely many strata and of a family of local systems on each stratum.
