A finiteness result for associated primes of local cohomology modules [PDF]

, 2000
We show that the first non-finitely generated local cohomology module Hi a (M ) of a finitely generated module M over a noetherian ring R with respect to an ideal a ⊆ R has only finitely many associated ...

Some results on cohomology modules with respect to an ideal and a non-negative integer [PDF]

Mathematica Bohemica
Let $R$ be a commutative Noetherian ring, $J$ an ideal of $R$, $M$ an $R$-module and let $d$ be a non-negative integer. In this paper we introduce a generalization of the notion of a local cohomology module, which we call a local cohomology module with ...

A Boothby–Wang Construction in Generalized Contact Geometry

Mathematische Nachrichten, EarlyView.
ABSTRACT We establish a generalized analogue of the Boothby–Wang theorem in generalized contact geometry, along with related results. We present a general method for constructing examples of generalized contact structures that are not of Poon–Wade type, and even examples that fail to be generalized contact structures.

Stable rational cohomology of automorphism groups of free groups and the integral cohomology of moduli spaces of graphs [PDF]

, 2002
It is not known whether or not the stable rational cohomology groups H*(Aut(F[infinity]);Q) always vanish (see Hatcher in [5] and Hatcher and Vogtmann in [7] where they pose the question and show that it does vanish in the first 6 dimensions).

ON THE COFINITENESS OF LOCAL COHOMOLOGY MODULES [PDF]

Journal of Algebraic Systems
Suppose that $\ab$ is an ideal of a given commutative Noetherian ring $R$ such that the $R$-modules $H^1_{\ab}(M)$ and $H^3_{\ab}(M)$ are $\ab$-cofinite, for every finitely generated $R$-modules $M$. In this paper, it is shown that the $R$-modules $H^i_{\

Establishing Shape Correspondences: A Survey

Computer Graphics Forum, EarlyView.
Abstract Shape correspondence between surfaces in 3D is a central problem in geometry processing, concerned with establishing meaningful relations between surfaces. While all correspondence problems share this goal, specific formulations can differ significantly: Downstream applications require certain properties that correspondences must satisfy ...

Equivariant Cohomology for Slice Groupoids and Its Local Linear Models

Mathematics
Let G be a compact Lie group acting smoothly on a manifold M. The local structure of such actions is described by the slice theorem, which reduces the study of G-spaces to smaller isotropy group actions.
