Abstract

We consider the direct and inverse scattering for the n-dimensional Schroedinger equation with a potential having no spherical symmetry. Sufficient conditions are given for the existence of a Wiener-Hopf factorization of the corresponding scattering operator. This factorization leads to the solution of a related Riemann-Hilbert problem which plays a key role in inverse scattering.
