Analytical and Numerical Solutions for Time-Fractional New Coupled mKdV Equation Arising in Interaction of Two Long Waves

The aim of this paper is to present new exact solution sets of nonlinear conformable time-fractional new coupled mKdV equations which arise in interaction of two long waves with different dispersion relations by means of sub-equation method.In addition, we also propose an analytical-approximate method namely residual power series method (RPSM) for the system.The fractional derivatives have been explained in newly defined conformable type, during the solution procedure.The exact solutions of the system obtained by the sub-equation method have been compared to approximate solutions derived by RPSM.The results showed that both methods are robust, dependable, easy to apply and a good alternative for seeking solutions of fractional partial differential equations.
