Abstract:
In the example of the Korteweg–de Vries equation, we consider the problem of extending the applicability of the inverse spectral transform method using delta-type potentials and their Darboux transformations. In this case, the problem of the properties of scattering data reduces to studying explicitly given entire functions of the spectral parameter.
Keywords:
inverse spectral problem, additional spectrum, Korteweg–de Vries equation, second Painlevé equation.
