[图书][B] Quasi-frobenius rings
WK Nicholson, MF Yousif - 2003 - books.google.com
A ring is called quasi-Frobenius if it is right or left selfinjective, and right or left artinian (all
four combinations are equivalent). The study of these rings grew out of the theory of …

When self-injective rings are QF: a report on a problem
C Faith, D Van Huynh - Journal of Algebra and its Applications, 2002 - World Scientific
Theorems of Osofsky and Kato imply that a right and left self-injective one-sided perfect ring
is quasi-Frobenius (= QF). The corresponding question for one-sided self-injective one or …

交换环上的极大性内射模
王芳贵, 汪明义, 杨立英 - 四川师范大学学报: 自然科学版, 2010 - cqvip.com
设R 是交换环, 表示R 的极大理想生成的乘法系, M 是R-模. 若对R 的任何极大理想m, 有ExtR1
(R/m, M)= 0, 则M 称为极大性内射模. 若R 自身为极大性内射模, 则R 称自极大性内射环 …

On generalizations of injectivity
J Chen, N Ding - International Symposium on Ring Theory, 2001 - Springer
Let R be a ring. The following results are proven. 1. If R is semilocal, right Kasch and right
simple-injective, then R is semiperfect, left and right finitely cogenerated. 2. If R is left perfect …

On generalizations of PF-rings
J Chen, N Ding, MF Yousif - Communications in Algebra, 2004 - Taylor & Francis
A ring R is called a right WPF-ring (weak PF-ring) if R is a semiperfect right simple-injective
ring with essential right socle. The class of right WPF-rings is broader than that of right PF …
