Exact Solutions Of Time Fractional Generalized Burgers-Fisher Equation Using Exp function and Exponential Rational Function Methods

Abstract

Using modified Riemann-Liouville derivative, the Exp function and Exponential rational function methods are implemented to solve the time-fractional generalized Burgers-Fisher equation (TF-GBF). The TF-GBF is transformed into a nonlinear ordinary differential equation (NLODE) by applying the transformation of traveling wave. The suggested methods are then introduced to formulate exact solutions for the resulting equation. The solutions are depicted using 2D and 3D plots.
