Resumen
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 asymptotically anti-deSitter and asymptotically flat spacetimes in three dimensions. In this context, Liouville theory is the two-dimensional conformal field theory that controls the boundary dynamics of asymptotically AdS3 spacetimes at the classical level. By taking a suitable limit of the coupling constants of the Hamiltonian formulation of Liouville, we construct and analyze a BMS3 invariant two-dimensional field theory.
