Fig. 9

The 3D, contour and 2D (when x = 1000) graphs for the multiple kink soliton solution \(\psi _{3, 3 }\) stated in (45), are plotted for \(\lambda := 1, \mu := 1, \nu := 1, \varrho := 0.45E^{-2},\) \(C:= 0.27E^{-2}, t:= 3, \omega _{0}:= 1, \omega _{1}:= 5, k_{1}:= 10\). This graph also shows axial perturbation.
