A ring R is a restricted right perfect ring if every proper homomorphic image of R is right perfect. A complete characterization of restricted right perfect group rings RG has been obtained when the f.c. center of the group G is nontrivial. The f.c. center of a group G is the set of all elements of G that have finitely many conjugates in G. |
