Cuspidal characters and automorphisms

Gunter Malle

Published 2017-02-26Version 1

We investigate the action of outer automorphisms of finite groups of Lie type on their irreducible characters. We obtain a definite result for cuspidal characters. As an application we verify the inductive McKay condition for some further infinite families of simple groups at certain primes.
