THE CLASS OF MODULES WITH PROJECTIVE COVER
Guo, Yong-Hua;

Abstract
Let R be a ring. A right R-module M is called perfect if M possesses a projective cover. In this paper, we consider the relationship between the class of perfect modules and other classes of modules. Some known rings are characterized by these relationships.
