Coartinianess of local homology modules for ideals of small dimension

Jingwen Shen, Pinger Zhang, Xiaoyan Yang

Let $a$ be an ideal of a commutative noetherian ring $R$ and $M$ an $R$ -module with Cosupport in $V (a)$ . We show that $M$ is $a$ -coartinia…

Modules cofinite with respect to ideals of small dimensions

Xiaoyan Yang, Jingwen Shen

Let $a$ be an ideal of a noetherian (not necessarily local) ring $R$ and $M$ an $R$ -module with $Supp_{R} M \subseteq V (a)$ . We show that if $\ma…

The $a$ -Filter grade of an ideal $b$ and $(a, b)$ - $f$ -modules

Jingwen Shen, Xiaoyan Yang

Let $a, b$ be two ideals of a commutative noetherian ring $R$ and $M$ a finitely generated $R$ -module.~We continue to study $\textrm{f}\textrm{-}\mathrm{grad}_…
