The connective K theory of semidihedral groups [PDF]

open access: yes, 2010
The real connective K-homology of finite groups ko¤(BG), plays a big role in the Gromov-Lawson-Rosenberg (GLR) conjecture. In order to compute them, we can calculate complex connective K-cohomology, ku¤(BG), first and then follow by computing complex ...

On the cominimaxness of generalized local cohomology modules

open access: yesScience and Technology Development Journal, 2020
The local cohomology theory plays an important role in commutative algebra and algebraic geometry. The I-cofiniteness of local cohomology modules is one of interesting properties which has been studied by many mathematicians. The I-cominimax modules is an extension of I-cofinite modules which was introduced by Hartshorne.

Cyclic cohomology after the excision theorem of Cuntz and Quillen [PDF]

open access: yes, 2013
The excision theorem of Cuntz and Quillen established the existence of a six term exact sequence in the bivariant periodic cyclic cohomology HP*(–,–) associated with an arbitrary algebra extension 0 ? S ? P ? Q ? 0.

Cofiniteness of generalized local cohomology modules [PDF]

open access: yesColloquium Mathematicum, 2004
Let $\fa$ denote an ideal of a commutative Noetherian ring $R$ and $M$ and $N$ two finitely generated $R$-modules with $\pd M< \infty$. It is shown that if $\fa$ is principal or $R$ is complete local and $\fa$ a prime ideal with $\dim R/\fa=1$, then the generalized local cohomology module $H^i_{\fa}(M,N)$ is $\fa$-cofinite for all $i \geq 0$.

COFINITENESS AND FINITENESS OF GENERALIZED LOCAL COHOMOLOGY MODULES [PDF]

open access: yesBulletin of the Australian Mathematical Society, 2009
AbstractLet I be an ideal of a commutative Noetherian local ring R, and M and N two finitely generated modules. Let t be a positive integer. We mainly prove that (i) if HIi(M,N) is Artinian for all i<t, then HIi(M,N) is I-cofinite for all i<t and Hom(R/I,HIt(M,N)) is finitely generated; (ii) if d=pd(M)<∞ and dim N=n<∞, then HId+n(M,N) is I ...

$S$-depth on $ZD$-modules and local cohomology [PDF]

open access: yes, 2021
summary:Let $R$ be a Noetherian ring, and $I$ and $J$ be two ideals of $R$. Let $S$ be a Serre subcategory of the category of $R$-modules satisfying the condition $C_I$ and $M$ be a $ZD$-module.

A generalized local cohomology theory

open access: yes, 2021
En este trabajo introducimos ciertos funtores de cohomología local que generalizan los estudiados en [9]. Demostramos que sus módulos de cohomología local pueden ser obtenidos como los módulos de cohomología de un complejo de Cech generalizado.
