摘要:

 利用比较和综合分析法得到了极大右理想作为右R-模是投射模的若干等价条件; 通过引入一个新定义MQ环, 由极大内射性和极大平坦性刻画了MQ环的性质; 总结了极大IF环的相关性质.

关键词:  极大内射模, 极大平坦模, MQ环, 极大IF环

Abstract:

 By means of comparison and analysis, some equivalent conditions of  the maximal right ideal as a module being a projective module were given firstly; then a new definition: MQ ring was introduced;  and the properties of MQ ring were discussed by max-injectivity and max\|flatness. Finally, the related properties of max-IF ring were summarized.

Key words: maxinjective module, maxflat module, MQ ring, maxIF ring
