Query: The Cauchy Problem of the Ward equation   We generalize the results of Villarroel, Fokas and Ioannidou, Dai, Terng and
Uhlenbeck to study the inverse scattering problem of the Ward equation with
non-small data and solve the Cauchy problem of the Ward equation with a
non-small purely continuous scattering data.
