Abstract

As a means of working towards solving the information paradox, we discuss conformal diagrams of evaporating black holes. We generalize the Schwarzschild solution to the asymptotically flat Bondi-metric and give a derivation of its asymptotic symmetry algebra, the BMS algebra. We discuss the interpretation as a charge algebra of zero-energy currents. Finally, we establish the centrally extended BMS-algebra as the semi-simple product of the Virasoro algebra acting on a representation.
