The space of positive scalar curvature metrics on the three-sphere

Friday, October 17, 2008 -
3:00pm to 5:00pm
In this talk we will discuss a proof of the path-connectedness of the space of positive scalar curvature metrics on the three-sphere. The proof uses the Ricci flow with surgery and the connected sum construction of Gromov and Lawson. The work of Perelman on Hamilton's Ricci flow is fundamental.
