From conjugacy classes in the weyl group to unipotent classes, III
MetadataShow full item record
Let G be an affine algebraic group over an algebraically closed field whose identity component G[superscript 0] is reductive. Let W be the Weyl group of G and let D be a connected component of G whose image in [G over G[superscript 0]] is unipotent. In this paper we define a map from the set of “twisted conjugacy classes” in W to the set of unipotent G[superscript 0]-conjugacy classes in D generalizing an earlier construction which applied when G is connected.
