On the realization of the Gelfand Character of a finite group as a twisted trace

Jorge Soto-Andrade, M. Francisca Yáñez

We show that the Gelfand character ${\chi }_G$ of a finite group $G$ (i.e. the sum of all irreducible complex characters of $G$ ) may be realized as a `` twisted trace'' $ g \mapsto Tr…
