Abstract

The `electromagnetic' $Sl(2;\bZ)$ duality group in spacetime dimension can be given a Kaluza-Klein interpretation in as the modular group of a compactifying torus. We show how dyonic -branes in can be interpreted as self-dual -branes in wound around the homology cycles of the torus. In particular, dyons of the D=4 N=4 heterotic string theory are interpreted as winding modes of a D=6 self-dual string, while D=8 dyonic membranes are interpreted as wound 3-branes of D=10 IIB superstring theory. We also discuss the T-dual IIA interpretations of D=8 dyonic membranes.
