Title: A Difference Approximation for Time Fractional Diffusion Equation
Abstract: From the relationship between the Caputo derivative and Grunwald derivative,the discretion for the fractional derivative is proposed by using the standard numerical approximation of Grunwald derivative.Then the difference approximation for the time fractional diffussion equation with initial conditions and boundary conditions is represented.The implicit difference approximation is unconditionally stable and convergent respectively.
