Geometry and Topology Seminar: Essential surfaces and how to find them

Presented by Matthias Nagel, University of Oxford

21 March 2019 13:00 in CM301

We recall the notion of an essential surface in a
3-manifold and explain how Culler-Shalen used
curves in the representation variety of SL(2,C) to construct them.
After generalizing this construction to SL(n,C) representations, we explain
how all essential surfaces can be obtained from this construction.

This is joint work with Stefan Friedl and Takahiro Kitayama.
