Odibat, Zaid Fractional power series solutions of fractional differential equations by using generalized Taylor series. (English) Zbl 1455.34009 Appl. Comput. Math. 19, No. 1, 47-58 (2020). Summary: In this paper, we present a brief survey of the generalized differential transform method. The main property of the method is its flexibility and ability to provide approximate solutions of nonlinear time and space-time fractional differential equations accurately and conveniently. Particular attention is paid to address the sufficient condition for convergence and to estimate the maximum absolute truncated error. Then, mainly, we present the fractional power series method as an efficient tool in obtaining fractional power series solutions. This method is introduced in a way that the generalized differential transform method can be considered as an iterative procedure to get the power series of the solution in terms of initial value parameters. The ideas described in this paper are expected to be further implemented to handle nonlinear models containing fractional derivatives.
