Three-dimensional Bondi-Metzner-Sachs invariant two-dimensional field theories as the flat limit of Liouville theory
Glenn Barnich, Andrés Gomberoff, Hernán A. González
In the gravitational context, Liouville theory is the two-dimensional conformal field theory that controls the boundary dynamics of asymptotically AdS_3 spacetimes at the classical…

The flat limit of three dimensional asymptotically anti-de Sitter spacetimes
Glenn Barnich, Andrés Gomberoff, Hernán A. González
In order to get a better understanding of holographic properties of gravitational theories with a vanishing cosmological constant, we analyze in detail the relation between asympto…
