摘要
引入了广义单内射环的概念,并证明了它是单内射环和n-(f-)内射环的真推广.研究了广义单内射环的一些性质,并用环的广义单内射性给出了QF的新刻画.特别地,推广了已知的相关结论.
We introduce general simple injective rings which are a generalization of simple injective rings and n- (f-) injective, and give some examples which show that n-(f-)simple injective rings neither simple injective nor n-(f-) injective. And characterizations of general simple injective rings are studied and provided. We also give several new characterizations of QF by using f-simple injectivity. Some known results are obtained as corollaries.
