Profile and contour plots of two breathers of second kind. (a) Evolution of the two-breather solution \(u^{(2)}_{bs}\) with parameters \(\alpha=1\), \(\epsilon=0\), \(\delta=1\), \(a=0\), \(\lambda_{1}=\frac{3}{4} i\), \(\lambda_{2}=\frac{4}{5} i\). (b) The corresponding density plot of \(u^{(2)}_{bs}\) in (a). (c) Evolution of the two-breather solution \(u^{(2)}_{bs}\) with parameters \(\alpha=1\), \(\epsilon=0\), \(\delta=1\), \(a=0\), \(\lambda_{1}=\frac{5}{4} i\), \(\lambda_{2}=\frac {3}{2} i\). (d) The corresponding density plot of \(u^{(2)}_{bs}\) in (c).
