nX-Coherent Rings

D Bennis - International Electronic Journal of Algebra, 2010 - dergipark.org.tr
This paper unifies several generalizations of coherent rings in one notion. Namely, we
introduce nX-coherent rings, where X is a class of modules and n is a positive integer, as …

FGT-injective dimensions of Π-coherent rings and almost excellent extension

Y Xiang - Proceedings-Mathematical Sciences, 2010 - Springer
We study, in this article, the FGT-injective dimensions of Π-coherent rings. If R is right Π-
coherent, and TI (resp. TF) stands for the class of FGT-injective (resp. FGT-flat) R-modules …

Y Xiang - Communications of the Korean Mathematical Society, 2010 - Citeseer
Let R be a ring and na fixed non-negative integer. TI n (resp. TF n) denotes the class of all
right R-modules of F GT-injective dimensions at most n (resp. all left R-modules of F GT-flat …
