Unknotting genus one knotsGeometry/Topology
|Speaker:||Alexander Coward, UC Davis|
|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.
