摘要
环R称为右NMP-内射环,如果对于每个由R的幂零元生成的主右理想到R的单同态都能扩充到R的一个自同态.左NMP-内射环可类似定义.本文我们首先引入并且刻画了NMP-内射环,说明了它是MP-内射环的真推广.然后研究了NMP-内射环的一些性质,推广了MP-内射环和ni-l内射环的一些已有结论.
A ring R is called right NMP- injective if every monomorphism from a principal right ideal to R can extend to an endomorphism of R. Left NMP- injective rings are defined analogusly. In this paper, we first introduce and characterize right NMP- injective rings, which are proper generalization of right MP- injective rings. Next, some properties of right N/V/P- injective rings are discussed. We extend some known results of MP- injective rings and nil- iniective rings.
