Central projective quaternionic representations
The authors approach the problem of classifying quaternionic projective representations of finite groups. Their study is based on a previous work by the same authors [Int. J. Theor. Phys. 34, 2491-2500 (1995; Zbl 0842.20016)] where it has been shown that the quaternionic projective representations of finite or compact groups fall into three classes: - types \({\mathbb R}, {\mathbb C}, {\mathbb Q}\) in their terminology. Here they prove first that there exists a one-to-one correspondence between the so called central projective quaternionic representations and the complex ones and then they prove that these representations can be identified with true representions of suitable extensions of the group under consideration.
