We give an argument showing that in N=4 supersymmetric gauge theories there exists at least one bound state saturating the Bogomol’nyi bound with electric charge p and magnetic charge q, for each p and q relatively prime, and we comment on the uniqueness of such state. This result is a necessary condition for the existence of an exact S-duality in N=4… CONTINUE READING
