Statistical entropy of four-dimensional rotating black holes from near-horizon geometry

We show that a class of four-dimensional rotating black holes allow five-dimensional embeddings as black rotating strings. Their near-horizon geometry factorizes locally as a product of the three-dimensional anti-de Sitter space-time and a two-dimensional sphere (AdS(3) x S-2), With angular momentum encoded in the global space-time structure. Following the observation that the isometries on the AdS(3) space induce a two-dimensional (super)conformal field theory on the boundary, we reproduce the microscopic entropy with the correct dependence on the black hole angular momentum.
