On top local cohomology modules, Matlis duality and tensor products

Autor: Sadeghi, M. Y., Eghbali, M., Ahmadi-Amoli, Kh.

Let $\mathfrak{a}$ be an ideal of a local ring $(R, \mathfrak{m})$ with $c = \mathrm{cd}(\mathfrak{a},R)$ the cohomological dimension of $\mathfrak{a}$ in $R$. In the case that $c=\dim R$, we first give a bound for depth~$D(H^c_\mathfrak{a}(R))$, whe

Some results on the local cohomology modules with respect to a pair of ideals

Autor: Aghapournahr, M., Ahmadi-amoli, Kh., Sadeghi, M. Y.

Some affirmative answers are given to Huneke's problems. The calculation of local cohomology modules with respect to an arbitrary pair of ideals $I,J$ can be reduced to calculation of local cohomology modules with respect to a pair of ideala whose fi

Upper bounds, cofiniteness, and artinianness of local cohomology modules defined by a pair of ideals

Autor: Aghapournahr, M., Ahmadi-amoli, KH., Sadeghi, M. Y.

Let $R$ be a commutative noetherian ring, $I,J$ be two ideals of $R$, $M$ be an $R$-module, and $\mathcal{S}$ be a Serre class of $R$-modules. A positive answer to the Huneke$^,$s conjecture is given for a noetherian ring $R$ and minimax $R$-module $

On the local cohomology modules deffined by a pair of ideals and serre subcategories

Autor: Ahmadi-Amoli, Kh., Sadeghi, M. Y.

This paper is concerned about the relation between local cohomology modules defined by a pair of ideals and Serre classes of R-modules, as a generalization of results of J. Azami, R. Naghipour and B. Vakili (2009) and M. Asgharzadeh and M.Tousi (2010
