Abstract
In this paper, a Kawahara equation is solved by using the Adomian’s decompositionmethod, modiï¬ed Adomian’s decomposition method, variational iteration method,modiï¬ed variational iteration method, homotopy perturbation method, modiï¬ed homotopyperturbation method and homotopy analysis method. The approximate solution of thisequation is calculated in the form of series which its components are computed byapplying a recursive relation. The existence and uniqueness of the solution and theconvergence of the proposed methods are proved. A numerical example is studied todemonstrate the accuracy of the presented methods.
