Rr. Gadylshin et Om. Kiselev, ON THE SOLITON-FREE STRUCTURE OF SCATTERING DATA ON PERTURBATION OF A2-DIMENSIONAL SOLITON FOR THE DAVEY-STEWARTSON EQUATION-II, Theoretical and mathematical physics, 106(2), 1996, pp. 167-173
The asymptotics of scattering data for the Davey-Stewartson equation I
I is obtained in the case of perturbation of a soliton. It is shown th
at the scattering data of the perturbed problem have a soliton-free ch
aracter.
