New soliton wave solutions of a (2+1)-dimensional Sawada-Kotera equation

In this work, we studied a (2 + 1)-dimensional Sawada-Kotera equation (SKE). This model depicts non -linear wave processes in shallow water, fluid dynamics, ion-acoustic waves in plasmas and other phenomena. A couple of well-established techniques, the Backlund transformation based on the modified Kudryashov method, and the Sardar-sub equation method are applied to obtain the soliton wave solution to the (2 + 1)-dimensional structure. To illustrate the behavior of the nonlinear model in an appealing fashion, a variety of travelling wave solutions are formed, such as contour, 2D, and 3D plots. The pro-posed approaches are proved more convenient and dominant for getting analytical solutions and can also be implemented to a variety of physical models representing nonlinear wave phenomena.(c) 2022 Shanghai Jiaotong University.
