Extreme Kerr throat geometry: A vacuum analog of AdS2×S2

Year: 1999
Type: article
Abstract: We study the near-horizon limit of a four-dimensional extreme rotating black hole. The limiting metric is a completely nonsingular vacuum solution, with an enhanced symmetry group $\mathrm{SL}(2,R)\ifmmode\times\else\texttimes\fi{}\mathrm{U}(1).$ We show that many of the properties of this solution are similar to the ${\mathrm{AdS}}_{2}{\ifmmode\times\else\texttimes\fi{}\mathrm{S}}^{2}$ geometry arising in the near-horizon limit of extreme charged black holes. In particular, the boundary at infinity is a timelike surface. This suggests the possibility of a dual quantum mechanical description. A five-dimensional generalization is also discussed.
