Figure 1. (a) The interaction between a half periodic wave and a kink soliton molecule. (b) The three-soliton molecule. (c) The soliton molecule consists of an asymmetry soliton and a one-soliton. (d) Wave propagation pattern of the wave along the x axis at the time t = −20, 0, 25 (from left to right).
