An introduction to the BV-BFV formalism
Speaker: Alberto Cattaneo
Time: 13:30 - 14:30
Abstract: The BV-BFV formalism unifies the BV formalism (which deals with the problem of fixing the gauge of field theories on closed manifolds) with the BFV formalism (which yields a cohomological resolution of the reduced phase space of a classical field theory). I will explain how this formalism arises and how it can be quantized.
From Conformal Field Theory to Geometry
Speaker: Luis Fernando Alday
Time:15:00 - 16:00
Abstract: The AdS/CFT correspondence maps correlators of local operators in a conformal field theory to scattering amplitudes in a gravitational/string theory on curved space-time. The study of such amplitudes is incredibly hard and has mostly been done in a certain classical limit. We show how modern analytic bootstrap techniques allows us to go much beyond that.
