Abstract
Recently, a new duality called the Kerr/CFT correspondence between four-dimensional non-supersymmetric but extremal Kerr black holes and a two-dimensional CFT was proposed, and the Bekenstein-Hawking entropy of the black holes was reproduced as the statistical entropy of the dual CFT using the Cardy formula. In this manuscript, we review the Kerr/CFT correspondence and explain our work on the generalization of this correspondence to fairly general black holes.
