The Einstein-Weyl Equations, Scattering Maps, and Holomorphic Disks

Friday, March 13, 2009 -
3:00pm to 5:00pm
This talk will show that conformally compact, globally hyperbolic, Lorentzian Einstein-Weyl 3-manifolds are in natural one-to-one correspondence with orientation-reversing diffeomorphisms of the 2-sphere. The proof hinges on a holomorphic-disk analog of Hitchin's mini-twistor correspondence.
