WebThis is the uniqueness of a construction of Einstein metrics given by M.Y. Wang and W. Ziller. It is pointed out that the uniqueness theorem also holds for a class of principal torus bundles and some uniqueness for principal bundles with non-abelian structure groups are given as well. The existence of Einstein metrics is given on some S²-bundles. WebOct 4, 2012 · The symmetry and topology of these solutions is compatible with those of black holes. The simplest examples give horizons of spatial topology S^3xS^2 or the non-trivial S^3-bundle over S^2. More generally, the horizons are Lens space bundles associated to certain principal torus-bundles over Fano Kaehler-Einstein manifolds.
