Symmetry Classification and Exact Solutions of a Variable Coefficient Space-Time Fractional Potential Burgers' Equation

We investigate the symmetry properties of a variable coefficient space-time fractional potential Burgers' equation. Fractional Lie symmetries and corresponding infinitesimal generators are obtained. With the help of the infinitesimal generators, some group invariant solutions are deduced. Further, some exact solutions of fractional potential Burgers' equation are generated by the invariant subspace method.
