Analysis of Multi Term Fractional Differential Equations using Variational Iteration Method

Amjad S. Shaikh, Vikas S. Jadhav, Bhausaheb R. Sontakke, Kottakkaran S. Nisar


In this paper, we have obtained an approximate solution ofmulti-term Caputo fractional differential equations (MFDEs) using theVariational iteration method (VIM). Further, we have obtained the convergencecriteria and error approximation of VIM for solving generalizedmulti term fractional differential equations. The obtained results areshown using plots to demonstrated the efficiency and accuracy of the VIM.
