Abstract

\We consider an inverse scattering problem for Schr\"odinger operators with energy dependent potentials. The inverse problem is formulated as a Riemann-Hilbert problem on a Riemann surface. A vanishing lemma is proved for two distinct symmetry classes. As an application we prove global existence theorems for the two distinct systems of partial differential equations ut+(u2/2+w)x=0,wt±uxxx+(uw)x=0u_t+(u^2/2+w)_x=0, w_t\pm u_{xxx}+(uw)_x=0 for suitably restricted, complementary classes of initial data.
