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

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...

We prove that for every abelian group G and every compactum X with dimG X ≤ n ≥ 2 there is a G-acyclic resolution r : Z −→ X from a compactum Z with dimG Z ≤ n and dimZ ≤ n + 1 onto X.
متن کاملRational acyclic resolutions
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.

that holds in the same generality as the universal coefficient theorem of Rosenberg and Schochet. There are advantages, in some circumstances, to using HomΛ(K(A),K(B)) in place of KK(A,B). These advantages derive from the fact that K(A) can be equipped with order and scale structures similar to those on K0(A). With this additional structure, the “Λ−module” K(A) becomes a powerful invariant of C...
