The spectrum of quarter BPS dyons in N = 4 supersymmetric string theories can change as the asymptotic moduli cross walls of marginal stability on which the dyon can break apart into a pair of half BPS states. In this paper we classify these marginal stability walls and examine this phenomenon in the context of exact dyon spectrum found in a class of N = 4 supersymmetric string theories. We argue that the dyon partition functions in different domains separated by marginal stability walls are…
