Approximate Solution of the Fitzhugh-Nagumo Equation by the Homotopy Analysis Method

摘要

In this paper, we used a different initial guess solution then others, to obtain very good approximate solution of the Fitzhugh-Nagumo equation by the homotopy analysis method. Thus, we further illustrate the freedom to select the initial guess solution, i.e. illustrate ffectiveness and convenience of homotopy analysis method.
