(Color online) Two-soliton interaction structures via the solutions (27) with parameters \(\lambda _{1}=\frac{1}{6}, \lambda _{2}=\frac{5}{2}, \alpha =1, C_{1,1}=1,C_{2,1}=2,C_{1,2}=1,C_{2,2}= \frac{1}{2}\). (a1)–(d1) The profiles of two-soliton solutions \(\tilde{u}_{n}, \tilde{p}_{n}, \tilde{v}_{n}\) and \(\tilde{x}_{n}\). (a2)–(d2) The propagation processes for \(\tilde{u}_{n}, \tilde{p}_{n}, \tilde{v}_{n}\) and \(\tilde{x}_{n}\) at \(t=-10 \) (dash-dotted line), \(t=0 \) (long dashed line) and \(t=10\) (solid line)
