Weyl symmetry and anomaly in asymptotically locally AdS_3

Abstract: I will discuss an enhancement of Brown-Henneaux boundary conditions in 3d AdS General Relativity to encompass Weyl transformations of the boundary metric. The consequences on the asymptotic symmetry algebra and the dual theory of imposing a conformally flat boundary condition are explored. In particular, I will show that the corresponding asymptotic symmetries include a new sector of Weyl rescalings with integrable but not conserved surface charges. The holographic counterpart of this result can be consistently described by an anomalous Ward-Takahashi identity in the boundary.
