Sign conjugacy classes of the symmetric groups

Lucia Morotti

A conjugacy class $C$ of a finite group $G$ is a sign conjugacy class if every irreducible character of $G$ takes value 0, 1 or -1 on $C$ . In this paper we classify the sign conjug…

$p$ -vanishing conjugacy classes of symmetric groups

Lucia Morotti

For a prime $p$ , we say that a conjugacy class of a finite group $G$ is $p$ -vanishing if every irreducible character of $G$ of degree divisible by $p$ takes value 0 on that conjuga…

Vanishing classes for $p$ -singular characters of symmetric groups

Lucia Morotti

We call an irreducible character $p$ -singular if $p$ divides its degree. We prove a number of equivalent conditions for a character of the symmetric group $S_{n}$ to be $p$ -singular,…
