Simple classical groups of Lie type are determined by their character degrees

Hung P. Tong-Viet

Let G be a finite group. Denote by Irr(G) the set of all irreducible complex characters of G. Let cd(G) be the set of all irreducible complex character degrees of G forgetting multiplicities, that is, cd(G)={χ(1):χ∈Irr(G)} and let X1(G) be the set of all irreducible complex character degrees of G counting multiplicities. Let H be a finite nonabelian simple classical group. In this paper, we will show that if G is a finite group and X1(G)=X1(H) then G is isomorphic to H. In particular, this implies that the nonabelian simple classical groups of Lie type are uniquely determined by the structure of their complex group algebras.

Symmetric groups are determined by their character degrees

Hung P. Tong-Viet

Abstract Let G be a finite group. Let X 1 ( G ) be the first column of the ordinary character table of G. In this paper, we will show that if X 1 ( G ) = X 1 ( S n ) , then G ≅ S n . As a consequence, we show that S n is uniquely determined by the structure of the complex group algebra C S n .
