Some results on generalized local cohomology modules

Alireza Vahidi, Moharram Aghapournahr

Let be a commutative Noetherian ring with non-zero identity, $\fa$ an ideal of , a finite --module and an arbitrary --module. Here, we show that, in the Serre…

On the vanishing and finiteness properties of generalized local cohomology modules

Moharram Aghapournahr

Let be a commutative noetherian ring, $\fa$ an ideal of and finite --modules. We prove that the following statements are equivalent. \begin{enumerate} \item[(i)] $…

Artinianness of local cohomology modules

Moharram Aghapournahr, Leif Melkersson

Let be a noetherian ring, $\fa$ an ideal of , and an --module. Some uniform theorems on the artinianness of certain local cohomology modules are proven in a general s…

Some results on local cohomology modules

Amir Mafi

Let be a commutative Noetherian ring, $\fa$ an ideal of , and let be a finitely generated -module. For a non-negative integer , we prove that $H_{\fa}^t(M)$ is $\f…

On the associated primes of generalized local cohomology modules

Amir Mafi

Let $\fa$ be an ideal of a commutative Noetherian ring with identity and let and be two finitely generated -modules. Let be a positive integer. It is shown that…
