Causal properties of AdS-isometry groups II: BTZ multi-black-holes
Pages: 1209 – 1257
This paper is the continuation of Causal properties of AdS-isometry groups I: causal actions and limit sets. We essentially prove that the family of strongly causal spacetimes defined in Causal properties of AdS-isometry groups I: causal actions and limit sets associated to generic achronal subsets in Ein2 contains all the examples of BTZ multi-blackholes. It provides new elements for the global description of these multiblack-holes. We also prove that any strongly causal spacetime locally modeled on the anti-de Sitter space admits a well-defined maximal strongly causal conformal boundary locally modeled on Ein2.
