Analytical solution of a fractional diffusion equation by variational iteration method
نویسنده
چکیده
In the present paper the Analytical approximate solution of a fractional diffusion equation is deducedwith the help of powerful Variational Iterationmethod. By using an initial value, the explicit solutions of the equation for different cases have beenderived,which accelerate the rapid convergence of the series solution. The present method performs extremely well in terms of efficiency and simplicity. Numerical results for different particular cases of the problem are presented graphically. © 2008 Elsevier Ltd.
