mit dem Thema: ''The scattering problem for 1D Schrödinger operators with
step-like periodic potential''

Abstract:
We develop the direct and inverse scattering theory for one-dimensional
Schrödinger operators with step-like potentials that are asymptotically
close to different finite-band periodic potentials on the different
half-axes. We give a characterisation of the scattering data, that allows us
to solve uniquely the inverse scattering problem in the prescribed class of
perturbations.
