On $G$ -character tables for normal subgroups

María José Felipe, María Dolores Pérez-Ramos, Víctor Sotomayor

Let $N$ be a normal subgroup of a finite group $G$ . From a result due to Brauer, it can be derived that the character table of $G$ contains square submatrices which are induced by…

On the Sylow graph of a group and Sylow normalizers

L. S. Kazarin, A. Martínez-Pastor, M. D. Pérez-Ramos

Let $G$ be a finite group and $G_{p}$ be a Sylow $p$ -subgroup of $G$ for a prime $p$ in $π (G)$ , the set of all prime divisors of the order of $G$ . The automiser $A_{p} (G)$ is defined t…
