Abstract

The exact spectrum of dyons in a class of N = 4 supersymmetric string theories is known to change discontinuously across walls of marginal stability. We show that the change in the degeneracy across the walls of marginal stability can be accounted for precisely by the entropy of two centered small black holes which (dis)appear as we cross the walls of marginal stability.
