Query: A numerical method for a class of nonlinear fractional
  advection-diffusion equations   In this note, a numerical method based on finite differences to solve a class
of nonlinear advection-diffusion fractional differential equation is proposed.
The fractional operator considered here is the fractional Riemann-Liouville
derivative or the fractional Riesz derivative of order $\alpha$. The
consistency and unconditionally stability of the method are shown. Finally, an
example of application of this method is presented.
