关于伪投射模的若干讨论

Some Discussions of the Pseudo-projective Modules

给出了伪投射模的另外一种等价定义,并对伪投射模的自同态环的Jacobson根做了讨论,还对伪投射盖做了某些探讨.

We give another equivalent definition of the pseudo-projective modules, and talked about the Jacobson radical of the endomorphism rings of the pseudo-projective modules. We also discussed the pseudo-projective covers of some modules.
