摘要：

The moduli space of static finite energy solutions to Ward's integrable chiral model is the space M-N of based rational maps from CP1 to itself with degree N. The Lagrangian of Ward's model gives rise to a Kahler metric and a magnetic vector potential on this space. However, the magnetic field strength vanishes, and the approximate non-relativistic solutions to Ward's model correspond to a geodesic motion on MN. These solutions can be compared with exact solutions which describe non-scattering or scattering solitons.
