Figure 4. (a) A three-dimensional plot of a mixed solution between soliton molecules and breathers with the parameters in equation (12) at t = 0; (c) a three-dimensional plot of a mixed breather-asymmetric soliton solution with the parameters in equation (12), except for φ2 = −3 at t = 0; (b) and (d) density plots of the mixed breather-soliton molecule solution and the mixed lump-soliton molecule solution.
