ABSTRACT

Let $G$ be a reductive connected group over an algebraic closure of finite field. In this paper we give the classification of character sheaves on $G$ in categorical terms (as a categorical centre). Previously such a classification was known for unipotent character sheaves and in the case where the ground field is replaced by the complex numbers.
