Inverse scattering on the half-line for energy-dependent Schrodinger equations

摘要

In this paper, we study the inverse scattering problem for energy-dependent Schrodinger equations on the half-line with energy-dependent boundary conditions at the origin. Under certain positivity and very mild regularity assumptions, we transform this scattering problem to the one for non-canonical Dirac systems and show that, in turn, the latter can be placed within the known scattering theory for ZS-AKNS systems. This allows us to give a complete description of the corresponding scattering functionsSfor the class of problems under consideration and justify an algorithm of reconstructing the problem fromS.
