Completion, Čech and local homology and cohomology: interactions between them

, 2018
The aim of the present monograph is a thorough study of the adic-completion, its left derived functors and their relations to the local cohomology functors, as well as several completeness criteria, related questions and various dualities formulas.

Associated primes of local cohomology and S2-ification

, 2012
Let R be commutative Noetherian, I⊂R an ideal, and M a finitely generated R-module. We prove that if R/P has an S2-ification for all P∈Spec(R) then the set of primes associated to the second local cohomology module HI2(M) is finite when ht(IR/P)≥2 for ...

Annihilators of Local Cohomology Modules

, 2011
In many important theorems in the homological theory of commutative local rings, an essential ingredient in the proof is to consider the annihilators of local cohomology modules.

On a Notion of Cohen-Macaulay and the Non-vanishing of Čech Cohomology Modules [PDF]

, 2017
In this paper, we study the Cohen-Macaulay property of a general commutative ring with unity defined by Hamilton and Marley. We give sufficient conditions on pullback constructions, fixed rings, and normal monoid rings to all be Cohen-Macaulay in this ...

Local cohomology and numerical semigroup rings

, 2001
Let R be a Noetherian ring, I an ideal of R, and M a finitely generated R-module. The i-th local cohomology module of M with respect to I, [special characters omitted](M), is of considerable interest, as it has many applications in commutative algebra ...

Stable Cohomology of Local Rings and Castelnuovo–Mumford Regularity of Graded Modules

, 2017
This thesis consists of two parts: 1) A bimodule structure on the bounded cohomology of a local ring (Chapter 1), 2) Modules of infinite regularity over graded commutative rings (Chapter 2).
