Scattering theory with finite-gap backgrounds: transformation operators and characteristic properties of scattering data
I. Egorova, J. Michor, and G. Teschl
Keywords: Inverse scattering, Jacobi operators, finite-gap, steplike.
Abstract: We develop direct and inverse scattering theory for Jacobi operators with steplike coefficients which are asymptotically close to different finite-gap quasi-periodic coefficients on different sides. We give a complete characterization of the scattering data, which allows unique solvability of the inverse scattering problem for perturbations with finite second moment.
