Abstract
Bogomol’nyi-Prasad-Sommerfield monopoles on correspond, via the generalized Nahm transform, to certain solutions of the Hitchin equations on the cylinder . The moduli space of two monopoles with their center of mass fixed is a four-dimensional manifold with a natural hyperkähler metric, and its geodesics correspond to slow-motion monopole scattering. The purpose of this paper is to study the geometry of in terms of the Nahm-Hitchin data, i.e., in terms of structures on . In particular, we identify the moduli, derive the asymptotic metric on , and discuss several geodesic surfaces and geodesics on . The latter include novel examples of monopole dynamics.
