%0 Journal Article %A Montesinos Amilibia, José María %T Open 3-manifolds and branched coverings: a quick exposition %D 2007 %@ 0034-7426 %U https://hdl.handle.net/20.500.14352/50763 %X This is a survey article discussing the author's work in a series of several publications on the relationship between 3-manifolds and wild knots in the 3-sphere and strings in R3 given by branched coverings. He includes an introduction to ordinary combinatorial branched coverings and a parallel introduction to the general topological branched coverings defined by R. H. Fox. Among other things one may conclude that every closed, oriented 3-manifold is a 3-fold covering of the 3-sphere branched over a wild knot. The paper ends with a brief discussion of two open problems. %~
