We implemented a variational method for approximating the solution to the nonlinear dispersive K (m, p, 1)-type equations. By 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 th

β¦ Synopsis
In this paper, He's variational iteration method is applied to obtain exact solutions of some nonlinear diffusion equations. The variational iteration method is used to construct correction functionals using general Lagrange multipliers identified optimally via the variational theory, and the initial approximations can be freely chosen with unknown constants. The solutions obtained are compared with those obtained by the Adomian decomposition method and homotopy perturbation method, showing excellent agreement, but the variational iteration method is more effective. He's variational iteration method can be introduced to overcome the difficulties arising in calculating Adomian polynomials.

In this work, we introduce a framework for obtaining exact solutions to linear and nonlinear diffusion equations. Exact solutions are developed for some diffusion processes of power law diffusitivies. He's variational iteration method (VIM) is used for analytic treatment of these equations. The powe
In this paper, the variational iteration method (VIM) is reintroduced with Laplace transforms and the PadΓ© technique treatment to obtain closed form solutions of nonlinear equations.
