Homomorphisms on Infinite Direct Products of Groups, Rings and Monoids
We study properties of a group, abelian group, ring, or monoid B which (a) guarantee that every homomorphism from an infinite direct product ∏ I Ai of objects of the same sort onto B factors through the direct product of finitely many ultraproducts of the Ai (possibly after composition with the natural map B → B/Z(B) or some variant), and/or (b) guarantee that when a map does so factor (and the...
متن کاملon varietal capability of infinite direct products of groups
recently, the authors gave some conditions under which a direct product of finitely many groups is $mathcal{v}-$capable if and only if each of its factors is $mathcal{v}-$capable for some varieties $mathcal{v}$. in this paper, we extend this fact to any infinite direct product of groups. moreover, we conclude some results for $mathcal{v}-$capability of direct products of infinitel...
متن کاملOn Cohomology rings of infinite groups
Let R be any ring (with 1), G a torsion free group and RG the corresponding group ring. Let Ext∗RG(M,M) be the cohomology ring associated to the RG-module M . Let H be a subgroup of finite index of G. The following is a special version of our main Theorem: Assume the profinite completion of G is torsion free. Then an element ζ ∈ Ext∗RG(M,M) is nilpotent (under Yoneda’s product) if and only if i...
متن کاملFamilies of Ultrafilters, and Homomorphisms on Infinite Direct Product Algebras
Criteria are obtained for a filter F of subsets of a set I to be an intersection of finitely many ultrafilters, respectively, finitely many κ-complete ultrafilters for a given uncountable cardinal κ. From these, general results are deduced concerning homomorphisms on infinite direct product groups, which yield quick proofs of some results in the literature: the Loś-Eda theorem (characterizing h...
متن کاملCohomology Rings of Almost-direct Products of Free Groups
An almost-direct product of free groups is an iterated semidirect product of finitely generated free groups in which the action of the constituent free groups on the homology of one another is trivial. We determine the structure of the cohomology ring of such a group. This is used to analyze the topological complexity of the associated Eilenberg-Mac Lane space. 1. Almost direct products of free...
