Linearization of local cohomology modules

The aim of this work is to describe the linear structure of regular holonomic $\mathcal D$-modules with support a normal crossing with variation zero introduced in [Local cohomology, arrangements of subspaces and monomial ideals, to appear in Adv.

COFINITENESS OF GENERALIZED LOCAL COHOMOLOGY MODULES

Bulletin of the Australian Mathematical Society, 2011
AbstractLet 𝔞 be an ideal of a Noetherian ring R. Let s be a nonnegative integer and let M and N be two R-modules such that ExtjR(M/𝔞M,Hi𝔞(N)) is finite for all i<s and all j≥0 . We show that HomR (R/𝔞,Hs𝔞(M,N)) is finite provided ExtsR(M/𝔞M,N) is a finite R-module.

Cominimaxness of generalized local cohomology modules

Bulletin of the Belgian Mathematical Society - Simon Stevin
This paper investigates the finiteness properties of generalized local cohomology modules. Let \(R\) be a commutative Noetherian ring with identity, and \(\mathfrak{a}\) an ideal of \(R\). For two \(R\)-modules \(X\) and \(Y,\) and an integer \(i\geq 0\), the \(i\)th \textit{generalized local cohomology} module of \(X\) and \(Y\) with respect to ...

Generalized local cohomology and regularity of Ext modules [PDF]

Journal of Algebra, 2008
Let R be a Noetherian standard graded ring, and M and N two finitely generated graded R-modules. We introduce regR(M,N) by using the notion of generalized local cohomology instead of local cohomology, in the definition of regularity. We prove that regR(M,
