Abstract

The Jordan decomposition of characters is a key component in Lusztig's classification of the representations of finite groups of Lie type that arise as the fixed points of a reductive group. We review this construction with emphasis on the case of GL(n,q), where the unipotent characters may be classified independently of the base field.
