Singular supports for character sheaves on a group compactification

Xuhua He, George Lusztig

Let $G$ be a semisimple adjoint group over $C$ and $G ˉ$ be the De Concini-Procesi completion of $G$ . In this paper, we define a Lagrangian subvariety $Λ$ of the cotangen…

Character sheaves on disconnected groups, VIII

G. Lusztig

In this paper we continue the study of character sheaves on a reductive group G. To each subset of the set of simple reflections in the Weyl group we associate an algebra of the sa…

Unipotent elements in small characteristic

G. Lusztig

We make a study of unipotent elements in a connected reductive group over an algebraically closed field with emphasis on the case where the characteristic is a bad prime. We try to…
