Abstract
In this paper, we present a presumably new approach in order to solve the time-fractional Drinfeld–Sokolov–Wilson system, which is based upon the Liouville–Caputo fractional integral (LCFI), the Caputo–Fabrizio fractional integral, and the Atangana–Baleanu fractional integral in the sense of the LCFI by using the Adomian decomposition method. We compare the approximate solutions with the exact solution (if available), and we find an excellent agreement between them. In the case of a non-integer order, we evaluate the residual error function, thereby showing that the order of the error is very small. In all of our calculations, we apply the software package, Mathematica (Version 9).
