Flat limit of three dimensional asymptotically anti–de Sitter spacetimes
Flat limit of three dimensional asymptotically anti–de Sitter spacetimes
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-de Sitter and asymptotically flat spacetimes in three dimensions. This relation is somewhat subtle because the limit of vanishing cosmological constant cannot be naively …
