摘要
本文通过对半自反模的引入,给出了SR-投射模的定义及相应命题,同时证明了内射模的一个等价定义,进而研究了SR-投射模与内射模之间的关系。
In this thesis,offering the definition of SR-projective modules and corresponding propositions,by means of introducing semi-reflexive modules,we have proved a definition of equal value of injective modules.And then we study the relationship between the SR-projective modules and injective modules.
