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…

Gorenstein projective, injective and flat modules over trivial ring extensions

Lixin Mao

We introduce the concepts of generalized compatible and cocompatible bimodules in order to characterize Gorenstein projective, injective and flat modules over trivial ring extensio…
