Unipotent elements in small characteristic, II
G. Lusztig
Let G be a special orthogonal group over an algebraically closed field of characteristic exponent p. In this paper we extend certain aspects of the Dynkin-Kostant theory of unipote…
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…
Character sheaves on disconnected groups, VII
G. Lusztig
We define and study convolution of parabolic character sheaves. As an application we attach to any parabolic character sheaf the orbit of a tame local system on the maximal torus u…
Character sheaves on disconnected groups, VI
G. Lusztig
We define the notion of character sheaf on a possibly disconnected reductive group. We show that the restriction functor carries a character sheaf to a direct sum of character shea…
Character sheaves on disconnected groups, V
G. Lusztig
We continue the study of character sheaves on a not necessarily connected reductive group. We prove orthogonality formulas for certain characteristic functions.
