For each cardinal κ, each natural number n and each simplicial
complex K we construct a space νκn(K) and a map $\pi \colon
\nu^n_\kappa(K) \to K$ such that the following conditions are satisfied.
- νκn(K) is a complete metric n-dimensional space of weight
κ.
- νκn(K) is an absolute neighborhood extensor in dimension n.
- νκn(K) is strongly universal in the class of n-dimensional
complete metric spaces of weight~κ.
- π is an n-homotopy equivalence.
For κ=ω the constructed spaces are n-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.
