Geometry Topology Working Seminar
Friday, October 13, 2017 - 13:55
1.5 hours (actually 80 minutes)
In this series of talks I will introduce branched coverings of manifolds and sketch proofs of most the known results in low dimensions (such as every 3 manifold is a 3-fold branched cover over a knot in the 3-sphere and the existence of universal knots). Along the way several open problems will be discussed.
