Abstract

We prove that Dranishnikov's kk-dimensional resolution dk ⁣:μkQd_k\colon \mu^k\to Q is a UVn1^{n-1}-divider of Chigogidze's kk-dimensional resolution ckc_k. This fact implies that dk1d_k^{-1} preserves ZZ-sets. A further development of the concept of UVn1^{n-1}-dividers permits us to find sufficient conditions for dk1(A)d_k^{-1}(A) to be homeomorphic to the N\"{o}beling space νk\nu^k or the universal pseudoboundary σk\sigma^k. We also obtain some other applications.
