Element orders and codegrees of characters in non-solvable groups

Z. Akhlaghi, E. Pacifici, L. Sanus

Given a finite group $G$ and an irreducible complex character $χ$ of $G$ , the codegree of $χ$ is defined as the integer $cod (χ) = ∣ G : ker χ ∣/ χ (1)$ . It was conjectured by G. Qian…

The blocks with five irreducible characters

J. Miquel Martínez, Noelia Rizo, Lucia Sanus

Let $G$ be a finite group, $p$ a prime and $B$ a Brauer $p$ -block of $G$ with defect group $D$ . We prove that if the number of irreducible ordinary characters in $B$ is $5$ then $D…
