“…Recently, Ma et al proposed the positive quadratic function to obtain the lump solutions, and some special examples of lump solutions have been found, such as the KdV equation [18,19], the KP equation [20,21], the BKP equation [22], the SK equation [23], the JM equation [24], the shallow water wave equation [25], the coupled Boussinesq equations [26], and nonlinear evolution equation [27,28]. More recently, high-order rogue waves in a variety of soliton equations have been studied, including the generalized Kadomtsev-Petviashvili equation [29], nonlinear Schrödinger equation [30][31][32][33], the Boussinesq equation [34], the breaking soliton equation [35], the Sasa-Satsuma equation [36], the Davey-Stewartson equations [37], the complex short pulse equation [38], and many other equations. More importantly, collision will happen among different solitons.…”
