Reduced dynamics of Ward solitons. (English) Zbl 1083.37055

The authors show that a geodesic motion on the moduli space of static solutions approximates the nonrelativistic dynamics of Ward solitons. These solutions are compared with the exact solutions which describe nonscattering or scattering solitons.
