Weyl charges in asymptotically locally AdS3 spacetimes in the framework of NMG

In this work, following the paper by Francesco Alessio, et al., [1], we consider Weyl transformations of the boundary metric in Feffermann-Graham gauge in new massive gravity. We construct the phase space, the analyze of the asymptotic structure and the asymptotic symmetry algebra. We show that the surface charges are finite, integrable but not necessarily conserved. Then, we obtain the charge algebra which involves the central extension.
