GVZ-groups with two character degrees
Published 29 Feb 2024 in math.GR | (2402.19003v2)
Abstract: We investigate the finite groups $G$ for which $\chi(1){2}=|G:Z(\chi)|$ for all characters $\chi \in Irr(G)$ and $|cd(G)|=2$. We obtain some alternate characterizations of these groups and we obtain some information regarding the structure of these groups.
