Projective G-groups

[摘要] It is known that the natural concept of projective representation of a group G has also significance for permutation representations (G-sets). In this paper the implications of the corresponding idea for G-groups are explored. As a consequence, different relations with some well-known concepts as crowns, wreath products, primitive groups, common complements and diagonal subgroups are obtained.
