Subnormalizers and character correspondences in $p$ -solvable groups

Gabriel A. L. Souza

A new family of local-global conjectures in the representation theory of finite groups has recently been proposed by Moretó. We show that one of the strongest of these conjectures,…

Height zero characters and Galois automorphisms

Alexander Moretó, Noelia Rizo, Gabriel A. L. Souza

Let $G$ be a finite group and let $p$ be a prime. In this paper, we prove a strengthened version of Brauer's height zero conjecture for the principal $p$ -block of $G$ that takes th…
