Abstract:

The physical model of generalized nonlinear disturbed Benjamin equation was considered. The homotopic mapping method was used to construct corresponding homotopic mapping. And then suitable initial approximation was selected, and the arbitrary order approximate solution of the soliton was calculated. A weakly disturbed equation was studied. The accuracy for the obtained approximate soliton was compared, and it was found that the obtained approximate soliton by the homotopic mapping method is of a good accuracy.

Key words: nonlinear, Benjamin equation, solitary wave, approximate analytic solution
