From: On quasi-integrable deformation scheme of the KdV system
The effect of quasi-deformation on the weak-coupling map from NLS to KdV solutions. The NLS single soliton (a) maps to a KdV soliton train (b), a property retained over the quasi-deformation (c,d). Herein, \(\varepsilon =1.5\), \(V=1=\rho\), \(X_0=0=T_0\) \(\xi =0.1\) and \(\omega _0=1=k_0\).
