GVZ-groups with two character degrees

Group Theory 2024-04-12 v2

Abstract

We investigate the finite groups GG for which χ(1)2=G:Z(χ)\chi(1)^{2}=|G:Z(\chi)| for all characters χIrr(G)\chi \in Irr(G) and cd(G)=2|cd(G)|=2. We obtain some alternate characterizations of these groups and we obtain some information regarding the structure of these groups.
