On The Eaton-Moretó Conjecture for Principal Blocks of Finite Groups

Asier Arranz, Javier Gómez-Serrano, Gabriel Navarro +1

Let $G$ be a finite group and let $p$ be a prime. If $P$ is a nonabelian Sylow $p$ -subgroup of $G$ and $m (P)$ is the smallest non-linear irreducible character degree of $P$ , we pro…

Real 2-blocks in quasi-simple groups

John Revere McHugh, A. A. Schaeffer Fry

We determine which quasi-simple groups have a non-principal $2$ -block that is stable under complex conjugation. As a corollary, we determine that the Mathieu group $M_{22}$ is the…
