A GPIU method for fractional diffusion equations

A GPIU method for fractional diffusion equations

Abstract The fractional diffusion equations can be discretized by applying the implicit finite difference scheme and the unconditionally stable shifted Grünwald formula. Hence, the generating linear system has a real Toeplitz structure when the two diffusion coefficients are non-negative constants....
