Coordinate independent approach to 5d black holes
  Five-dimensional generalization of (A)dS(5)-Kerr black hole is shown to be generated in a coordinate free way by a single AdS(5) global symmetry parameter. Its mass and angular momenta are associated to Casimir invariants of the background space-time symmetry parameter leading to the black hole classification scheme similar to that of relativistic fields resulting apart from ordinary black hole to "tachyonic" and "light-like" ones.
