NEAR HORIZON GEOMETRY OF ROTATING BLACK-HOLES IN 5 DIMENSIONS

We interpret the general rotating black holes in five dimensions as ro tating black strings in six dimensions. In the near-horizon limit the geometry is locally AdS(3) x S-3, as in the non-rotating case. However , the global structure couples the AdS(3) and the S-3, giving angular velocity to the S-3. The asymptotic geometry is exploited to count the microstates and recover the precise value of the Bekenstein-Hawking e ntropy, with rotation taken properly into account. We discuss the pert urbation spectrum of the rotating black hole, and its relation to the underlying conformal field theory. (C) 1998 Elsevier Science B.V.
