由于DNLS方程的约斯特解不倾向于自由约斯特解,如b| | !1、必须对常用的逆散射变换(IST)进行修正。除了Kaup和Newell的方法,我们提出了一个简单的修正来构造IST方程,其中通常的Zakharov-Shabat kern是通过乘以2或1来修正的。为了证明修正的合理性,我们证明所得到的约斯特解确实满足相容性方程对。
Since the Jost solutions of the DNLS equation does not tend to the free Jost solutioins as | | ! 1, the usual inverse scattering transform (IST) must be revised. Beside the Kaup and Newell's approach, we propose a simple revision in constructing the equations of IST, where the usual Zakharov-Shabat kern is revised by multiplying 2 or 1 . To justify the revision we show that the Jost solutions obtained do satisfy the pair of compatibility equations.
