Novel interaction phenomena of the new (2+1)-dimensional extended shallow water wave equation

Based on the Hirota bilinear method, we study some kinds of novel interaction solutions of the new integrable (2 + 1)-dimensional extended shallow water wave equation. Using the symbolic computations, we obtain a rich variety of exact solutions such as the lump solutions, lump-kink solutions, breather solutions and two-kink solutions and these exact solutions are shown analytically and graphically by selecting the proper parameters. These new exact solutions contribute us to our understanding of the physical phenomena of the integrable nonlinear shallow water wave model.
