“…Due to the complexity of various nonlinear equations, there is no single method for solving them. For integrable systems, effective methods have been developed, such as the inverse scattering method [1,2], the Hirota method [3][4][5], the Painleve method [6,7], Bäcklund transformations [8][9][10][11] and the mapping and deformation method [2]. Bäcklund transformations are an example of differential geometric structures generated by differential equations.…”
