(Weyl-)Fefferman-Graham asymptotic symmetries
Speaker:Arnaud Delfante (Universite de Mons)
Abstract:Within the framework of asymptotic symmetries as applied to the AdS/CFT correspondence, there is an increasing body of evidence suggesting that the symmetries employed for gauge-fixing might carry charge. Consequently, setting the associated fields to zero is a physical constraint on the system, which should be avoided. In this talk, we will examine a partial fixing of the Fefferman-Graham (FG) gauge, referred to as the Weyl-Fefferman-Graham (WFG) gauge, which restores boundary Weyl covariance. We will show that the diffeomorphism mapping WFG to FG can be charged and discuss how this relates to holography.
