Numerical method for fractional sub-diffusion equation with space–time varying diffusivity and smooth solution
Using a new generalized L2 formula and a time varying compact finite difference operator, we construct a high order numerical scheme for a class of generalized fractional diffusion equation with space–time varying diffusivity that admits a smooth solution. The convergence order is shown to be O(τz3−...
