Approximate Analytical Solutions of the Fractional Sharma-Tasso-Olver Equation Using Homotopy Analysis Method and a Comparison with Other Methods

Abstract

In this paper, the homotopy analysis method (HAM) is successfully applied to the fractional Sharma-Tasso-Olver equation to obtain its approximate analytical solutions. Comparison of the obtained results with those of variational iteration method (VIM), Adomian’s decomposition method (ADM) and homotopy perturbation method (HPM) has led us to conclude that the method gives significantly important consequences. The HAM solution includes an auxiliary parameter ~ which provides a convenient way of adjusting and controlling the convergence region of solution series.
