Abstract

For each cardinal κ\kappa, each natural number nn and each simplicial complex KK we construct a space νκn(K)\nu^n_\kappa(K) and a map π ⁣:νκn(K)K\pi \colon \nu^n_\kappa(K) \to K such that the following conditions are satisfied. 1. νκn(K)\nu^n_\kappa(K) is a complete metric nn-dimensional space of weight κ\kappa. 2. νκn(K)\nu^n_\kappa(K) is an absolute neighborhood extensor in dimension nn. 3. νκn(K)\nu^n_\kappa(K) is strongly universal in the class of nn-dimensional complete metric spaces of weight~κ\kappa. 4. π\pi is an nn-homotopy equivalence. For κ=ω\kappa = \omega the constructed spaces are nn-dimensional separable N\"obeling manifolds. The constructed spaces have very interesting fractal-like internal structure that allows for easy construction, subdivision, and surgery of brick partitions.
