Some Results on Graded Generalized Local Cohomology Modules
Journal of Mathematical Extension, 2010 . Let R = ⊕n>0Rn be a graded Noetherian ring with local base ring R0 and let R+ = ⊕n>1Rn. Let M and N be finitely generated graded R-modules. In this paper we extend some of the known results about ordinary local cohomology modules Hi R+ (M) to ...

The group of endotrivial modules in the normal case. [PDF]
, 2007 The group of endotrivial modules has recently been determined for a finite group having a normal Sylow $p$-subgroup. In this paper, we give and compare three different presentations of a torsion-free subgroup of maximal rank of the group of endotrivial ...

A generalization of the finiteness problem of the local cohomology modules [PDF]
Czechoslovak Mathematical Journal, 2014 This paper is in the series of works which study the finiteness of the associated prime of local cohomology modules \(H^i_{\mathfrak {a}}(M)\), where \(\mathfrak {a}\) is an ideal of a commutative Noetherian ring \(R\) and \(M\) is an \(R\)-module. In general Ass\((H^i_{\mathfrak {a}}(M))\) is not finite for any \(i\), \(\mathfrak {a}\) and \(M\), e.g.

On Finiteness Properties of Local Cohomology Modules [PDF]
, 2022 openThis thesis has its foundations in the fields of homological and commutative algebra, in particular in the study of local cohomology. Local cohomology was introduced by Grothendieck in the early 1960s, in part to answer a conjecture of Pierre Samuel ...

One the P-Adic Local Invariant Cycle Theorem [PDF]
, 2012 The aim of this paper is to consider the $p$-adic local invariant cycle theorem in the mixed characteristic case. In the first part of the paper, via case-by-case discussion, we construct the $p$-adic specialization map, and then write out the ...

Artinianness of formal local cohomology modules [PDF]
, 2019 summary:Let ${\frak{a}}$ be an ideal of Noetherian local ring $(R,{\frak{m}})$ and $M$ a finitely generated $R$-module of dimension $d$. In this paper we investigate the Artinianness of formal local cohomology modules under certain conditions on the ...

General formal local cohomology modules [PDF]
Algebra and Discrete Mathematics, 2020 Let (R,m) be a local ring, Φ a system of ideals of R and M a finitely generated R-module. In this paper, we define and study general formal local cohomology modules. We denote the ith general formal local cohomology module M with respect to Φ by FiΦ(M) and we investigate some finiteness and Artinianness properties of general formal local cohomology ...
