Decompactification near the horizon and non-vanishing entropy

Abstract

Intersecting D-brane configurations are related to black holes in D=4. Using the standard way of compactification only the Reissner-Nordstrøm black hole is non-singular. In this paper we argue, that also the other black holes are non-singular if i) we compactify over a periodic array and ii) we allow the string metric after reaching a critical curvature to choose the dual geometry. Effectively this means that near the horizon the solution completely decompactifies and chooses a non-singular D-brane configuration.
