Abstract |
|
This note is devoted to proving the theorem that every right quasi-projective module over a semi-primary ring R has the double centralizer property if and only if R is a direct sum of primary rings, and to discussing some of its consequences. In particular, this theorem places a strong necessary condition on a large class of the balanced rings of Camillo which are both a specialization of Thrall’s QF − l rings and a generalization of the uniserial rings of Köthe. |
