Twisted Frobenius-Schur Indicators and Character Degree Sums in Dihedral Groups

Venkata Subbaiah Yerrapati, Rahul Dixit, Ajay Kumar Shukla

Let $G$ be a finite group and $T(G)$ be the sum of the degrees of its irreducible complex representations. We investigate the relationship between $T(G)$ and the number of twisted…
