Finite groups whose prime graphs are regular
Hung P. Tong-Viet
Let G be a finite group and let Irr(G) be the set of all irreducible complex characters of G. Let cd(G) be the set of all character degrees of G and denote by ρ(G) the set of prime…
Complex group algebras of the double covers of the symmetric and alternating groups
Christine Bessenrodt, Hung Ngoc Nguyen, Jørn B. Olsson +1
We prove that the double covers of the alternating and symmetric groups are determined by their complex group algebras. To be more precise, let be an integer, a finit…
Groups with some arithmetic conditions on real class sizes
Hung P. Tong-Viet
Let G be a finite group. An element x in G is a real element if x is conjugate to its inverse in G. For x in G, the conjugacy class x^G is said to be a real conjugacy class if ever…
Groups whose prime graphs have no triangles
Hung P. Tong-Viet
Let G be a finite group and let cd(G) be the set of all complex irreducible character degrees of G Let ρ(G) be the set of all primes which divide some character degree of G. The pr…
