equation

One of the important nonlinear evolution equations in mathematical physics is the modified Kawahara equation. In this work, by utilizing an analytic method based on the Jacobi elliptic functions, a group of exact solutions of the fractional modified Kawahara equation had been found. The method can be applied to all of the time, space and space-time fractional equations. Four problems had also been given to demonstrate the application of the method and some solutions had been illustrated by the graphics. (C) 2020 Elsevier B.V.
