SUMMARY:Gravity as a diffeomorphism invariant SU(2) gauge theory - Kirill 
 Krasnov (Nottingham)

DESCRIPTION:I will describe how geometry and its dynamics can be described
  using an SU(2) gauge field instead of the metric. This works in 4 spaceti
 me dimensions and is based on the self-duality. The advantage of this new 
 gauge-theoretic formalism is that the (linearised) description of graviton
 s is much simpler than in the metric language. This simplicity relies on a
  certain complex of differential operators. I will also touch on the compu
 tation of the gravitational one-loop effective action in this language.
