Solving Some Fractional Partial Differential Equations by Invariant Subspace and Double Sumudu Transform Methods

Abstract

In this paper, several types of space-time fractional partial differential equations has been solved by using most of special double linear integral transform” double Sumudu ”. Also, we are going to argue the truth of these solutions by another analytically method “invariant subspace method”. All results are illustrative numerically and graphically.
