Associated primes of local cohomology modules and Matlis duality

K Bahmanpour, R Naghipour - Journal of Algebra, 2008 - Elsevier
Let (R, m) be a commutative Noetherian local ring of dimension d and I an ideal of R. We
show that the set of associated primes of the local cohomology module HI2 (R) is finite …

Jónsson modules over Noetherian rings

G Oman - Communications in Algebra®, 2010 - Taylor & Francis
Let R be a commutative ring with identity, and let M be an infinite unitary R-module. M is said
to be a Jónsson module provided every proper submodule of M has strictly smaller …

On the endomorphism ring of the canonical module

Y Aoyama, S Goto - Journal of Mathematics of Kyoto University, 1985 - projecteuclid.org
A ring will always mean a commutative ring with unit. Let R be a noetherian ring, M a finitely
generated R-module and N a submodule of M. We denote by MinR (M) the set of all minimal …

[PDF][PDF] Modules cofinite with respect to an ideal

L Melkersson - Journal of Algebra, 2005 - core.ac.uk
We continue the study of modules cofinite with respect to an ideal of a (noetherian
commutative) ring. Hartshorne [8] introduced this class of modules, answering in negative a …

Extension functors of local cohomology modules and Serre categories of modules

N Abazari, K Bahmanpour - 2015 - projecteuclid.org
Let (R,m) be a complete Noetherian local ring, I a proper ideal of R and M, N two finitely
generated R-modules such that Supp (N)⊆V(I). Let t≧0 be an integer such that for each …

Criteria for flatness and injectivity

N Epstein, Y Yao - Mathematische Zeitschrift, 2012 - Springer
Let R be a commutative Noetherian ring. We give criteria for flatness of R-modules in terms
of associated primes and torsion-freeness of certain tensor products. This allows us to …

Cofiniteness of local cohomology modules for a pair of ideals for small dimensions

M Aghapournahr - Journal of Algebra and Its Applications, 2018 - World Scientific
Let R be a commutative Noetherian ring, I and J be two ideals of R and M be an R-module
(not necessary I-torsion). In this paper among other things, it is shown that if dim M≤ 1, then …

Attached primes of the top generalized local cohomology modules

Y Gu, L Chu - Bulletin of the Australian Mathematical Society, 2009 - cambridge.org
Let (R, 𝔪) be a commutative Noetherian local ring, let I be an ideal of R and let M and N be
finitely generated R-modules. Assume that,. First, we give the formula for the attached …
