New Periodic Wave, Cross-Kink Wave, Breather, and the Interaction Phenomenon for the (2 + 1)‎-Dimensional Sharmo–Tasso–Olver Equation

الملخص EN

In this paper, with the aid of symbolic computation, several kinds of exact solutions including periodic waves, cross-kink waves, and breather are proposed by using a trilinear form for the (2 + 1)-dimensional Sharmo–Tasso–Olver equation.

Then, by combing the different forms, the interactions between a lump and one-kink soliton and between a lump and periodic waves are generated.

Moreover, the dynamic characteristics of interaction solutions are analyzed graphically by selecting suitable parameters with the help of Maple.
