On w-copure projective modules

Refat Abdelmawla Khaled Assaad, Mohammed Tamekkante, Lixin Mao

Let $R$ be a commutative ring. An $R$ -module $M$ is said to be $w$ -split if Ext $_{R}^{1} (M, N)$ is a GV-torsion $R$ -module for all $R$ -modules $N$ . It is known that every projective m…

On $τ_{q}$ -weak global dimensions of commuative rings

Xiaolei Zhang, Ning Bian, Refat Abdelmawla Khaled Assaad +1

In this paper, the $τ_{q}$ -weak global dimension $τ_{q}$ -\cwd $(R)$ of a commutative ring $R$ is introduced. Rings with $τ_{q}$ -weak global dimension equal to $0$ are studied in terms of…

A note on weak w-projective modules

Refat Abdelmawla Khaled Assaad

Let $R$ be a ring. An $R$ -module $M$ is said to be a weak $w$ -projective module if $Ext_{R}^{1} (M, N) = 0$ for all $N \in P_{w}^{†_{\infty}}$ (see, \cite{FLQ}). In thi…

$w$ - $FP$ -projective modules and dimension

Refat Abdelmawla Khaled Assaad, El Mehdi Bouba, Mohammed Tamekkante

Let $R$ be a ring. An $R$ -module $M$ is said to be an absolutely $w$ -pure module if and only if $\Ext^1_R(F,M)$ is a GV-torsion module for any finitely presented module $F$ . In thi…
