Unipotent Supports for Finite Reductive Groups
The notion of unipotent support gives a canonical way of attaching to every irreducible character of a finite reductive group a unique unipotent conjugacy class of the ambient algebraic group. When the centre of the algebraic group is connected unipotent supports have been put to good use by a numerical relationship that was originally noticed by Lusztig. We will discuss an extension of this relationship to the case where the centre of the algebraic group is disconnected and an application of this extension.
