Abstract

We provide a realization of the AdS2/CFT1 correspondence in terms of asymptotic symmetries of the AdS2×S1 and AdS2×S2 geometries arising in near-extremal BTZ and Reissner-Nordström black holes. Cardy's formula exactly accounts for the deviation of the Bekenstein-Hawking entropy from extremality. We also argue that this result can be extended to more general black holes near extremality.
