Representing open 3-manifolds as 3-fold branched coverings.

José María Montesinos-Amilibia (2002)

Revista Matemática Complutense

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.

Two-fold branched coverings of S have type six.

Maria Rita Casali (1992)

Revista Matemática de la Universidad Complutense de Madrid

Similarity:

In this work, we prove that every closed, orientable 3-manifold M which is a two-fold covering of S branched over a link, has type six.
