A note on the injective dimension of local cohomology modules

M Hellus - Proceedings of the American Mathematical Society, 2008 - ams.org
For a Noetherian ring $ R $ we call an $ R $-module $ M $ cofinite if there exists an ideal $ I
$ of $ R $ such that $ M $ is $ I $-cofinite; we show that every cofinite module $ M $ satisfies …

[PDF][PDF] Cofinite modules and generalized local cohomology

A Mafi, H Saremi - Houston J. Math, 2009 - academia.edu
Let R be a commutative Noetherian ring, α an ideal of R, and M, N two finitely generated R-
modules. We prove that the generalized local cohomology modules Ht α (M, N) are α …

On the cofiniteness of local cohomology modules

K Bahmanpour, R Naghipour - Proceedings of the American Mathematical …, 2008 - ams.org
In this note we show that if $ I $ is an ideal of a Noetherian ring $ R $ and $ M $ is a finitely
generated $ R $-module, then for any minimax submodule $ N $ of $ H^{t} _ {I}(M) $ the $ R …

Cofiniteness of generalized local cohomology modules

K Divaani-Aazar, R Sazeedeh - arXiv preprint math/0408163, 2004 - arxiv.org
Let $\fa $ denote an ideal of a commutative Noetherian ring $ R $ and $ M $ and $ N $ two
finitely generated $ R $-modules with $\pd M<\infty $. It is shown that if $\fa $ is principal or …

Cofiniteness of local cohomology modules over regular local rings

G Chiriacescu - Bulletin of the London Mathematical Society, 2000 - cambridge.org
It is well known that for a Noetherian ring R, an ideal I of R, and M a finitely generated R-
module, the local cohomology modules HiI (M) are not always finitely generated. On the …
