MONTESINOS-AMILIBIA, JOSÉ MARÍA. Open 3-manifolds and branched coverings: a quick exposition. Rev.colomb.mat. [online]. 2007, vol.41, n.2, pp.287-302. ISSN 0034-7426.
Branched coverings relate closed, orientable 3-manifolds to links in S3, and open, orientable 3-manifolds to strings in S3\smallsetminus T, where T is a compact, totally disconnected tamely embedded subset of S3. Here we give the foundations of this last relationship. We introduce Fox theory of branched coverings and state the main theorems. We give examples to illustrate the theorems.
