Contributions to the theory of subnormal subgroups and factorized groups

Abstract

The purpose of this thesis is to investigate some problems concerning products of groups, that is given a group G with subgroups H and K. We investigate what effect the structures of H and K have on the the structure of the product HK. In chapters 2 and 3 we consider the case where the product is itself a group and in chapter 4 we consider the case where the product need not be a group
