The Schur indices of the cuspidal unipotent characters of the finite unitary groups

Abstract

Let Fq be a finte field with q elements of number :/: p. characteristic p. Let G be a connected, reductive Using this corollary, we can determine the algebraic group, defind over Fq, of type (2An_l), rationality of the generalized Gelfand-Graev rep- n _ 2, and let F :G G be the corresponding resentations of Un(Fq) (Kawanaka
