Conformal Symmetry for Black Holes in Four Dimensions
arXiv:1112.4846 · doi:10.1007/JHEP09(2012)076
Abstract
We show that the asymptotic boundary conditions of general asymptotically flat black holes in four dimensions can be modified such that a conformal symmetry emerges. The black holes with the asymptotic geometry removed in this manner satisfy the equations of motion of minimal supergravity in five dimensions. We develop evidence that a two dimensional CFT dual of general black holes in four dimensions account for their black hole entropy.
