The inverse scattering transform for weak Wigner-von Neumann type potentials (2203.13325v1)
Published 24 Mar 2022 in math-ph and math.MP
Abstract: In the context of the Cauchy problem for the Korteweg-de Vries equation we extend the inverse scattering transform to initial data that behave at plus infinity like a sum of Wigner-von Neumann type potentials with small coupling constants. Our arguments are based on the theory of Hankel operators.
