Extremal RN/CFT in both hands revisited

Abstract

We study RN/CFT correspondence for four dimensional extremal Reissner-Nordstrom black hole. We uplift the 4d RN black hole to a 5d rotating black hole and make a geometric regularization of the 5d space-time. Both hands central charges are obtained correctly at the same time by Brown-Henneaux technique. (C) 2016 The Authors. Published by Elsevier B.V.
