Abstract


Variational iteration method and homotopy perturbation
method are introduced to solve the Kawahara equation. Comparison of
the obtained results with the numerical solution shows that both
methods lead to remarkably accurate solutions. The main property of
the both methods is its flexibility and ability to solve nonlinear
equations accurately and conveniently.

Keywords


Variational iteration method; homotopy perturbation method; Kawahara equation; approximat solution; exact solution
