AB - <p style="text-align: justify;">A finite difference method which is second-order accurate in time and in
space is proposed for two-dimensional fractional percolation equations. Using the
Fourier transform, a general approximation for the mixed fractional derivatives is analyzed.
An approach based on the classical Crank-Nicolson scheme combined with
the Richardson extrapolation is used to obtain temporally and spatially second-order
accurate numerical estimates. Consistency, stability and convergence of the method
are established. Numerical experiments illustrating the effectiveness of the theoretical
analysis are provided.</p>
