$p$ -groups with exactly four codegrees

Sarah Croome, Mark L. Lewis

Let $G$ be a $p$ -group and let $χ$ be an irreducible character of $G$ . The codegree of $χ$ is given by $∣ G : ker (χ) ∣/ χ (1)$ . Du and Lewis have shown that a $p$ -group with exact…

$p$ -groups with $p^{2}$ as a codegree

Sarah Croome, Mark L. Lewis

Let $G$ be a $p$ -group and let $χ$ be an irreducible character of $G$ . The codegree of $χ$ is given by $∣ G : ker (χ) ∣/ χ (1)$ . This paper investigates the relationship between th…

Character codegrees of maximal class p-groups

Sarah Croome, Mark L. Lewis

Let $G$ be a $p$ -group and let $χ$ be an irreducible character of $G$ . The codegree of $χ$ is given by $∣ G : ker (χ) ∣/ χ (1)$ . If $G$ is a maximal class $p$ -group that is normall…
