Fractional Sumudu decomposition method for solving PDEs of fractional order

In this paper, the fractional Sumudu decomposition method (FSDM) is employed to handle the time-fractional PDEs and system of time-fractional PDEs. The fractional derivative is described in the Caputo sense. The approximate solutions are obtained by using FSDM, which is the coupling method of fractional decomposition method and Sumudu transform. The method in general is easy to implement and yields good results. Illustrative examples are included to demonstrate the validity and applicability of the proposed technique.
