| Abstract: | We consider the problem of coupling between a quotient module A/C
A
(G) and a submodule A(ωRG), where G is a group, R is a ring, and A is an RG-module; C
A
(G) can be considered as an analog of the center of the group, and the submodule A(ωRG) can be considered as an analog of the derived subgroup of the group.
