Abstrakt

We provide a classification of Lambda > 0-vacuum spacetimes which admit a Killing vector field with respect to which the associated 'Mars-Simon tensor' (MST) vanishes and have a conformally flat I- (or I+). To that end, we also give a complete classification of conformal Killing vector fields on the 3-sphere S-3 up to Mobius transformations shedding light on the two fundamental constants that characterize the family of Kerr-de Sitter-like spacetimes, which turn out to be well-defined geometrical invariants. The topology of I is determined in every case, and a characterization result at I of the Kerr-de Sitter family presented.
