Let aa be an ideal of a commutative Noetherian ring R and M a finitely generated R-module.
It is shown that\rm Ann _R (H_ a^\rm dim M (M))=\rm Ann _R (M/T_R (a, M)) Ann R (H a dim …

Finiteness properties of minimax and coatomic local cohomology modules

M Aghapournahr, L Melkersson - Archiv der Mathematik, 2010 - Springer
Let R be a noetherian ring, a an ideal of R, and M an R-module. We prove that for a finite
module M, if\rm H^ i _ a (M) is minimax for all i≥ r≥ 1, then\rm H^ i _ a (M) is artinian for i≥ …

Associated and attached primes of local cohomology modules over almost Dedekind domains

N Pakyari, R Nekooei, E Rostami - Communications in Algebra, 2023 - Taylor & Francis
In this paper, we prove the Grothendieck's Vanishing Theorem for finitely generated ideals
over almost Dedekind domains and show that there exists a non-finitely generated prime …
