Deformations of General Relativity

Kirill Krasnov

2010-05-05

"I will describe a very special (infinite-parameter) family of gravity theories that all describe, exactly like General Relativity, just two propagating degrees of freedom. The theories are obtained by generalizing Plebanski's self-dual (chiral) formulation of GR. I will argue that this class of gravity theories provides a potentially powerful new framework for testing the asymptotic safety conjecture in quantum gravity."

This Perimeter seminar video became available yesterday. I still can't watch it because the Flash version is not yet online.
