چکیده

Let X be a compactum such that dimQ X ≤ n, n ≥ 2. We prove that there is a Q-acyclic resolution r : Z −→ X from a compactum Z of dim ≤ n. This allows us to give a complete description of all the cases when for a compactum X and an abelian group G such that dimGX ≤ n, n ≥ 2 there is a G-acyclic resolution r : Z −→ X from a compactum Z of dim ≤ n.

Universal acyclic resolutions for finitely generated coefficient groups

We prove that for every compactum X and every integer n ≥ 2 there are a compactum Z of dim ≤ n and a surjective UV n−1-map r : Z −→ X having the property that: for every finitely generated abelian group G and every integer k ≥ 2 such that dimG X ≤ k ≤ n we have dimG Z ≤ k and r is G-acyclic, or equivalently: for every simply connected CW-complex K with finitely generated homotopy groups such th...

Linearity Defects of Modules over Commutative Rings

This article concerns linear parts of minimal resolutions of finitely generated modules over commutative local, or graded rings. The focus is on the linearity defect of a module, which marks the point after which the linear part of its minimal resolution is acyclic. The results established track the change in this invariant under some standard operations in commutative algebra. As one of the ap...
