Unknotting genus one knots
Geometry/Topology| Speaker: | Alexander Coward, UC Davis |
| Location: | 2112 MSB |
| Start time: | Tue, Feb 3 2009, 4:10PM |
In this talk we will describe how to classify all unknotting crossing changes of genus one knots. The technology used is a combination of sutured manifold theory, some classical topology and an analysis of the arc complex of the once punctured torus.
