摘要
文中将投射模、内射模进行推广,引入A-投射模,A-内射模的概念,并且分别研究了它们的一些性质,由此构造出一种环,称为A-半单环,充分体现模对环的刻画.
This paper will promote projective modules and injective modules, introduce the concepts of A - injective module, A -projective module, and study their basic properties, thus construct a new ring, called A - semi - simple - ring, fully embody the module depicts of the ring.
