A new fourth-order grouping iterative method for the time fractional sub-diffusion equation having a weak singularity at initial time
A new fourth-order explicit grouping iterative method is constructed for the numerical solution of the fractional sub-diffusion equation. The discretization of the equation is based on fourth-order finite difference method. Captive fractional discretization having functions with a weak singularity a...
