Abstract
We consider the class of --modules where is an associative ring. Let be a module over a group ring where is a group and let be a set of all proper subgroups of such that if then belongs to . We study an --module such that , , , and is one of the classes: artinian --modules, minimax --modules, finite --modules. We consider the cases: 1) is a class of all artinian --modules, is either a ring of integers or a ring of --adic integers; 2) is a class of all minimax --modules, is a ring of integers, G is a locally soluble group; 3) is a class of all finite --modules, is an associative ring. In these cases we prove that is isomorphic to a quasi--cyclic --group for some prime .
