Application of Extended Fan Sub-Equation Method To Time FractionalBurgers-Fisher Equation

Abstract

The extended Fan sub-equation method applies in this paper obtain exact solutions of the generalized time fractional Burgers-sher equation.By appliying this method, we obtain dierent solutions that are benefit to further comprise the concepts of complex nonlinear physical phenomena.This method is simple, and can be applied to several nonlinear equations.Fractional derivatives are taken as in the sense of Jumarie's modied Riemann-Liouville derivative. The method is reliable and gives greater generality exact solutions than the existing methods. In tis work we use Mathematica for computations and programming.
