Exact and analytical solution for nonlinear dispersive K(m,p)K(m,p) equations using homotopy perturbation method

In the present Letter, we have implemented a homotopy perturbation method to approximately solve the nonlinear dispersive K(m,p)K(m,p) type equations. Using this scheme, the explicit exact solution is calculated in the form of a quickly convergent series with easily computable components. To illustrate the application of this method, numerical results are derived by using the calculated components of the variational series. The obtained results are found to be in good agreement with the exact solutions.
