Phys. Rev. Lett. 78, 1858–1860 (1997)Understanding the Area Proposal for Extremal Black Hole EntropyReceived 30 October 1996; published in the issue dated 10 March 1997 Whereas the usual understanding is that the entropy of only a nonextremal black hole is given by the area of the horizon, there are derivations of an area law for extremal black holes in some model calculations. It is explained here how such results can arise in an approach where one sums over topologies and imposes the extremality condition after quantization. © 1997 The American Physical Society URL:
