Unknotting genus one knots


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.
