Long-range Scattering Matrix for Schrödinger-type Operators
arXiv:1804.05488 · doi:10.2140/apde.2022.15.1725
Abstract
We show that the scattering matrix for a class of Schrödinger-type operators with long-range perturbations is a Fourier integral operator with the phase function which is the generating function of the modified classical scattering map.
