Geometry Topology Working Seminar
Friday, October 27, 2017 - 13:00
1.5 hours (actually 80 minutes)
Notice the seminar is back to 1.5 hours this week.
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). This week we should be able to finish our discussion of branched covers of surfaces and transition to 3-manifolds.
