Bass numbers of local cohomology modules with respect a pair of ideals

Sh. Payrovi, M. Lotfi Parsa, S. Babaei

Let $R$ be a Noetherian local ring, $I$ and $J$ two ideals of $R$ , $M$ an $R$ -module and $s$ and $t$ two integers. We study the relationship between the Bass numbers of $M$ and $H^…

Regular sequences and local cohomology modules with respect to a pair of ideals

Sh. Payrovi, M. Lotfi Parsa

Let $R$ be a Noetherian ring, $I$ and $J$ two ideals of $R$ and $t$ an integer. Let $S$ be the class of Artinian $R$ -modules, or the class of all $R$ -modules $N$ with $\dim_RN\leq…

Regular sequences and ZD-modules

Sh. Payrovi, M. Lotfi Parsa

Let R be a Noetherian ring, I an ideal of R and M a ZD-module. Let S be a Melkersson subcategory with respect to I such that M/IM doesn't belong to S. We show that all maximal S-se…
