LOW-ENERGY DYNAMICS OF N=2 SUPERSYMMETRIC MONOPOLES

lt is argued that the lw-energy dynamics of k-monopoles in N = 2 super symmetric Yang-Mills theory are determined by an N = 4 supersymmetric quantum mechanics based on the moduli space of k static monople soluti ons. This generalises Manton's ''geodesic approximation'' for studying the low-energy dynamics of (bosonic) BPS monopoles. We discuss some a spects of the quantisation and in particular argue that Dolbeault coho mology classes of the moduli space are related to bound states of the full quantum field theory.
