Using the ‘Riemann Problem with zeros’ method, Ward has constructed exact solutions to a –dimensional integrable Chiral Model, which exhibit solitons with nontrivial scattering. We give a correspondence between what we conjecture to be all pure soliton solutions and certain holomorphic vector bundles on a compact surface.
