关于P-投射模

On P-projective Modules

本文引入了P-投射模,n-p-投射模,Gp-投射模概念.由此构造了两种特殊的环:n-p-半单环与Gp-半单环,并用新引入的模对它们分别进行了刻化.

In this paper, We introduce the P-projective modules, n-p-projective modules, Gp- projective modules.Furdermore,we define two kinds of special rings： n-p-semisimple rings and Gp-semisimple rings. Then use the new modules to characterize n-p-semisimple rings and Gp-semisimple rings.
