Darboux Transformations for Bi-integrable Couplings of the AKNS System
摘要
We construct Darboux transformations for bi-integrable couplings of soliton equations. Then we apply the resulting theory to a kind of bi-integrable couplings of the AKNS systems. Particularly, we present exact one-soliton-like solutions for the bi-integrable couplings of the nonlinear Schrödinger equations.
