Projective (or spin) representations of finite groups. II

Tatsuya Tsurii, Satoe Yamanaka, Itsumi Mikami +1

In the previous paper, we proposed a practical method of constructing explicitly representation groups $R (G)$ for finite groups $G$ , and apply it to certain typical finite groups $…

Projective (or spin) representations of finite groups. I

Takeshi Hirai, Itsumi Mikami, Tatsuya Tsurii +1

Schur multiplier $M (G)$ of a finite group $G$ has been studied heavily. To proceed further to the study of projective (or spin) representations of $G$ and their characters (called…
