Universal acyclic resolutions for arbitrary coefficient groups
Michael Levin
Abstract
We prove that for every compactum X and every integer n ≥ 2 there are a compactum Z of ≤ n+1 and a surjective UVn-1-map r: Z X such that for every abelian group G and every integer k ≥ 2 such that G X ≤ k ≤ n we have G Z ≤ k and r is G-acyclic.
