Classical and Gravitational Aspects of the AdS3/CFT2 Correspondence

Glenn Barnich (Université Libre de Bruxelles)

It is shown in detail how conformal symmetries emerge in 3 dimensional asymptotically anti-de Sitter spacetimes in the sense of Fefferman-Graham. A new modified Lie bracket is introduced that allows one to disentangle the conformal rescalings of the boundary metric from its conformal isometries. Centrally extended representations of the asymptotic symmetries on solution space and in terms of canonical generators are also discussed.
