Multiple quadrate soliton solutions and chaotic behaviours of (2+1)-dimensional breaking soliton equation

With the projective equation method and the variable separation method, new exact solutions of the (2+1)-dimensional breaking soliton equation is derived. Based on the derived solitary wave excitation, we obtain multi-quadrate soliton structures with Weierstrassp function and study the chaotic behaviours of the equation for two chaotic systems.
