Abstract:

To study one type of the generalized DGH equation with strong dispersive term, the improved Fan subequation method was used to investigate the exact travelling wave solutions with the aid of MAPLE. As a result, two sets of parameters constraints and all bifurcation structure of sub-equation were obtained. Based on qualitative analysis, abundant solutions including the solitary wave solutions, kink wave solutions and periodic wave solutions were obtained, with the wave profiles of these solutions given as well.

Key words: generalized DGH equation with strong dispersive term; improved Fan subequation method, solitary wave solution, kink wave solution, periodic wave solution
