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 for finite groups , and apply it to certain typical finite groups $…
Projective (or spin) representations of finite groups. III
Satoe Yamanaka, Tatsuya Tsurii, Itsumi Mikami +1
In previous papers I and II under the same title, we proposed a practical method called Efficient stairway up to the Sky, and apply it to some typical finite groups , with Schur…
Projective (or spin) representations of finite groups. I
Takeshi Hirai, Itsumi Mikami, Tatsuya Tsurii +1
Schur multiplier of a finite group has been studied heavily. To proceed further to the study of projective (or spin) representations of and their characters (called…
Hypergroups arising from characters of a compact group and its subgroup
Hebert Heyer, Satoshi Kawakami, Tatsuya Tsurii +1
The purpose of the present paper is to investigate a hypergroup arising from irreducible characters of a compact group G and a closed subgroup of G with finite index. The convoluti…
