Action of automorphisms on irreducible characters of groups of type \textsf{A}

Farrokh Shirjian, Ali Iranmanesh

Let $G$ be a finite group isomorphic to $S{L}_n(q)$ or $S{U}_n(q)$ for some prime power $q$. In this paper, we give an explicit description of the action of automorphisms of $G$ on the…
