Simplest Equation Method for nonlinear solitary waves in Thomas-Fermi plasmas

The Thomas-Fermi (TF) equation has proved to be useful for the treatment of many physical phenomena. In this paper, the traveling wave solutions of the KdV equation is investigated by the simplest equation method. Also, the e ect of di erent parameters on these solitary waves is considered. The numerical results is conformed the good accuracy of presented method.
