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 $I ¨ $ - $w$ -P-flat modules, which can be seen as generalizations of both $I ¨ $ -P-flat modules and $w$ -P-flat modules. In particular,…

Some remarks on almost projective envelopes

Xiaolei Zhang, Wei Qi, Dechuan Zhou

Let $R$ be a commutative ring. An $R$ -module $M$ is said to be almost projective if $Ext_{R}^{1} (M, N) = 0$ for any $R_{m}$ -module $N$ and any maximal ideal $\mathfrak…
