DARBOUX TRANSFORMATION AND MULTI-SOLITON SOLUTIONS OF PRINCIPAL CHIRAL AND WZW MODELS

Modern Physics Letters A, 2011
In this paper we present Darboux transformation for the principal chiral and WZW models in two dimensions and construct multi-soliton solutions in terms of quasideterminants. We also establish the Darboux transformation on the holomorphic conserved currents of the WZW model and expressed them in terms of the quasideterminant.

Exact multi-soliton solution of the Benjamin-Ono equation

Journal of Physics A: Mathematical and General, 1979
An exact multi-soliton of the Benjamin-Ono equation is presented. The asymptotic form of the solution for large time is also given.

Multi-soliton solutions of coupled nonlinear Schrödinger Equations

Chinese Physics Letters, 1987
The 1+1 and 1+1+1 soliton solutions with different polarization for coupled nonlinear Schrodinger (NLS) Equations have been obtained by using Bilinear Method. The asymptotic behaviour and the polarization of these solutions are discussed.
