Abstract
In this paper, an application of homotopy perturbation method is applied to finding the solutions of the seven-order Sawada-Kotera (sSK) and a Lax’s seven-order KdV (LsKdV) equations. Then obtain the exact solitary-wave solutions and numerical solutions of the sSK and LsKdV equations for the initial conditions. The numerical solutions are compared with the known analytical solutions. Their remarkable accuracy are finally demonstrated for the both seven-order equations.
