Some remarks concerning the covering numbers of closed manifolds.
Representing open 3-manifolds as 3-fold branched coverings.

Similarity:
It is proved that the Freudenthal compactification of an open, connected, oriented 3-manifold is a 3-fold branched covering of S, and in some cases, a 2-fold branched covering of S. The branching set is a locally finite disjoint union of strings.
