Kerr/CFT correspondence

The Kerr/CFT correspondence is an extension of the AdS/CFT correspondence or gauge-gravity duality to rotating black holes (which are described by the Kerr metric).[1]

The duality works for black holes whose near-horizon geometry can be expressed as a product of AdS3 and a single compact coordinate. The AdS/CFT duality then maps this to a two-dimensional conformal field theory (the compact coordinate being analogous to the S5 factor in Maldacena's original work), from which the correct Bekenstein entropy can then be deduced.[2]

The original form of the duality applies to black holes with the maximum value of angular momentum, but it has now been speculatively extended to all lesser values.[3]
