Figure 4From: Darboux transformation of the general Hirota equation: multisoliton solutions, breather solutions, and rogue wave solutions Profile and contour plots of four solitons. (a) Evolution of the four-soliton solution \(u^{(4)}_{ss}\) via Eq. (45) with parameters \(\alpha=1\), \(\epsilon =1\), \(\delta=1\), \(\lambda_{1}=i\), \(\lambda_{2}=2 i\), \(\lambda_{3}= 4 i\), \(\lambda _{4}= 3 i\). (b) The corresponding density plot of \(u^{(4)}_{ss}\) in (a).Back to article page
