### Abstract

We develop a theory of Nöbeling manifolds similar to the theory of Hilbert space manifolds. We show that it reflects the theory of Menger manifolds developed by M. Bestvina and is its counterpart in the realm of complete spaces. In particular we prove the Nöbeling manifold characterization conjecture. We define the $n$-dimensional universal Nöbeling space $\nu ^n$ to be the subset of $R^{2n+1}$ consisting of all points with at most $n$ rational coordinates. To enable comparison with the infinite dimensional case we let $\nu ^\infty$ denote the Hilbert space. We define an $n$-dimensional Nöbeling manifold to be a Polish space locally homeomorphic to $\nu ^n$. The following theorem for $n = \infty$ is the characterization theorem of H. Toruńczyk. We establish it for $n < \infty$, where it was known as the Nöbeling manifold characterization conjecture. Characterization theorem. An $n$-dimensional Polish ANE($n$)-space is a Nöbeling manifold if and only if it is strongly universal in dimension $n$. The following theorem was proved by D. W. Henderson and R. Schori for $n = \infty$. We establish it in the finite dimensional case. Topological rigidity theorem. Two $n$-dimensional Nöbeling manifolds are homeomorphic if and only if they are $n$-homotopy equivalent. We also establish the open embedding theorem, the $Z$-set unknotting theorem, the local $Z$-set unknotting theorem and the sum theorem for Nöbeling manifolds.
