Abstract
In this research, we focus on some novel exact solutions of the new (2 + 1)-dimensional shallow water wave equation (SWWE). First, the soliton molecules on the (x,y)-, (x,t)- and (y,t)-planes are constructed via assigning the velocity resonance conditions to the multiple soliton solutions (MSSs) that can be derived via the Hirota method. Second, the periodic wave solutions are explored by means of the new homoclinic approach. Finally, the other diverse wave solutions including the kink wave, singular wave and the singular periodic wave solutions are also plumbed by the sub-equation approach (SEA). The dynamic performances of the extracted solutions are presented graphically to unveil the nonlinear physical characteristics. As we know, the extracted solutions in this paper are all new and have not been investigated in other literature, which can help us make sense of the nonlinear dynamics of the new (2 + 1)-dimensional SWWE better.
