A generalized character related to the local structure and representation theory of a finite group

Geoffrey R. Robinson

We consider the generalized character $Ψ_{1, p, G}$ of a finite group $G$ which vanishes on all $p$ -singular elements of $G$ and whose value at each $p$ -regular $y \in G$ is the numb…

A group-theoretic condition equivalent to a condition on principal blocks

Geoffrey R. Robinson

In this note, we give a group-theoretic condition which is equivalent to the fact that the trivial character is the only complex irreducible character of a finite group G which is…
