Abstract:
A nonconservative, reflectionless inverse scattering problem is discussed on an energy dependent Schrödinger equation. A scattering transform from the potential of the equation to the reflectionless scattering data is completely characterized by a function induced from a Gelfand-Levitan-Marchenko equation, with an expression of the inverse scattering transform in terms of the function. Based upon the inverse scattering theory, we establish an inverse scattering method by which $N$-soliton solutions of a nonlinear evolution system (Boussinesq system) are constructed.

Keywords: Inverse scattering theory, reflectionless potential, energy dependent Schrödinger equation, nonlinear evolution system, soliton solution, Boussinesq system.
