On the structure of some modules over generalized soluble groups
Let R be a ring and G a group. An R-module A is said to be Artinian-by-(finite rank) if TorR(A) is Artinian and A/ TorR(A) has finite R-rank. We study a module A over a group ring RG such that A/CA(H) is Artinian-by-(finite rank) (as an R-module) for every proper subgroup H.
