Cohomological dimension of Mackey functors for infinite groups [PDF]
We consider the cohomology of Mackey functors for infinite groups and define the Mackey-cohomological dimension of a group G. We relate this dimension to other cohomological dimensions such as the Bredon cohomological dimension and the relative ...

ON THE COMINIMAXNESS OF LOCAL COHOMOLOGY MODULES [PDF]
Let I be an ideal of a commutative Noetherian ring R. It is shown that the R-modules Hi I (M) are I-cominimax, for all finitely generated R-modules M and all i ∈ N0, if the R-modules Hi I (R) are I-cofinite with dimension not exceeding 1, for all ...

Determining the cohomological dimension of certain compacta [PDF]
In previous work of this author and of John J. Walsh it was shown that many of the known examples of hereditarily infinite dimensional compacta have infinite cohomological dimension.

Separable ring extensions and cohomological dimension [PDF]
Our purpose here is to obtain generalizations of several results on cohomological dimension of algebras due to M. Auslander, Eilenberg, Rosenberg, and Zelinsky in which the notion of separable algebra plays a significant role. The generalization consists

Topological calculation of local cohomological dimension [PDF]
We show that the sum of the local cohomological dimension and the rectified $\mathbb Q$-homological depth of a closed analytic subspace of a complex manifold coincide with the dimension of the ambient manifold.

Two-sided homological properties of special and one-relator monoids
A monoid presentation is called special if the right-hand side of each defining relation is equal to 1. We prove results which relate the two-sided homological finiteness properties of a monoid defined by a special presentation with those of its group of

Bounding The Hochschild Cohomological Dimension [PDF]
Ce mémoire a deux objectifs principaux. Premièrement de développer et interpréter les groupes de cohomologie de Hochschild de basse dimension et deuxièmement de borner la dimension cohomologique des k-algèbres par dessous; montrant que presque aucune ...

Diophantine and cohomological dimensions [PDF]
We give explicit linear bounds on the p p -cohomological dimension of a field in terms of its Diophantine dimension.
