On strongly --Flat modules and Their Homological Dimensions
Wei Qi, Xiaolei Zhang, Wei Zhao
In this paper, we introduce and study the notion of strongly --flat modules. The --weak global dimension --w.gl.dim of an NP-ring is also introduced and…
Uniformly -Noetherian rings
Wei Qi, Hwankoo Kim, Fanggui Wang +2
Let be a ring and a multiplicative subset of . Then is called a uniformly -Noetherian (--Noetherian for abbreviation) ring provided there exists an element…
On --Flat modules and Their Homological Dimensions
Xiaolei Zhang, Wei Zhao
In this paper, we introduce and study the class of --flat modules which are generalizations of both -flat modules and -flat modules. The --weak global dimension $…
New Characterizations of -coherent rings
Wei Qi, Xiaolei Zhang, Wei Zhao
In this paper, we introduce and study the class --ML of -Mittag-Leffler modules with respect to all flat modules. We show that a ring is -coherent if and…
Signless Laplacian spectral radius and fractional matchings in graphs
Yingui Pan, Jianping Li
A fractional matching of a graph is a function giving each edge a number in such that for each vertex , where is the se…
