Approximate Analytic Solutions of Time-Fractional Hirota-Satsuma Coupled KdV Equation and Coupled MKdV Equation

الملخص EN

By introducing the fractional derivative in the sense of Caputo and combining the pretreatment technique to deal with long nonlinear items, the generalized two-dimensional differential transform method is proposed for solving the time-fractional Hirota-Satsuma coupled KdV equation and coupled MKdV equation.

The presented method is a numerical method based on the generalized Taylor series expansion which constructs an analytical solution in the form of a polynomial.

The numerical results show that the generalized two-dimensional differential transform method is very effective for the fractional coupled equations.
