Egorova, I.; Michor, J.; Teschl, G. Scattering theory for Jacobi operators with general step-like quasiperiodic background. (English) Zbl 1177.47038 J. Math. Phys. Anal. Geom. 4, No. 1, 33-62 (2008). The authors develop direct and inverse scattering theory for Jacobi operators with step-like coefficients which are asymptotically close to different finite-gap quasiperiodic coefficients on different sides. They also give a complete characterization of the scattering data, which allow unique solvability of the inverse scattering problem in the class of perturbations with finite first moment.
