Abstract: Denote by the subspace of the Hilbert cube consisting of for all but finitely many }. Then following characterization of manifolds modeled on is proven and applied to cell-like, upper semicontinuous decompositions of -manifolds. An ANR is a -manifold if and only if (a) is the countable union of finite-dimensional compacta, (b) each compact subset of is a strong -set, and (c) for each positive integer , every mapping can be arbitrarily closely approximated by an injection.
