Abstract

We investigate soliton solutions of the Toda hierarchy on a quasi‐periodic finite‐gap background by means of the double commutation method and the inverse scattering transform. In particular, we compute the phase shift caused by a soliton on a quasi‐periodic finite‐gap background. Furthermore, we consider short range perturbations via scattering theory. We give a full description of the effect of the double commutation method on the scattering data and establish the inverse scattering transform in this setting (© 2009 WILEY‐VCH Verlag GmbH & Co.

In this paper we consider the nonlinear third-order quasi-linear differential equation and obtain some simple conditions for the existence of a periodic solution for it. In so doing we use the implicit function theorem to prove a theorem about the existence of periodic solutions and consider one ex
