Application of coupled modified simplest equation method to solve space-time fractional coupled Burger’s equation

One of the topics of curiosity in recent years in miscellaneous sciences such as physics and engineering is to attain analytical solutions to evolution equations. In this work, a novel modification of the simplest equation method has been suggested to solve the nonlinear fractional system of the partial differential equation. As an example, the proposed methods have been applied to achieve the exact solutions of the space-time fractional coupled Burger’s equation.
