Inverse Scattering Theory for One-Dimensional Schrödinger Operators with Steplike Finite-Gap Potentials

Anne Boutet de Monvel, Iryna Egorova, and Gerald Teschl

Abstract
We develop direct and inverse scattering theory for one-dimensional Schrödinger operators with steplike potentials which are asymptotically close to different finite-gap potentials on different half-axes. We give a complete characterization of the scattering data, which allow unique solvability of the inverse scattering problem in the class of perturbations with finite second moment.
