Some remarks on $u$ - $S$ -Noetherian and $u$ - $S$ -coherent rings

Xiaolei Zhang, Wei Qi

In this paper, we give some new characterizations of $u$ - $S$ -Noetherian rings and $u$ - $S$ -coherent rings in terms of uniform $S$ -version of injective precovers, flat preenvelopes a…

A new version of P-flat modules and its applications

Wei Qi, Xiaolei Zhang

In this paper, we introduce and study the class of $ϕ$ - $w$ -P-flat modules, which can be seen as generalizations of both $ϕ$ -P-flat modules and $w$ -P-flat modules. In particular, we…

Two remarks on Almost Projective Modules

Xiaolei Zhang, Wei Qi, Dechuan Zhou

For a commutative ring $R$ , an almost projective module is a module whose localization at every maximal ideal is free, with no restriction on rank. We prove that every almost proje…
