The adi galerkin finite element method is proved to be convergent in time and in the l 2 norm in space. The convergence order is 𝓞(k ln k + h r), where k is the temporal grid size and h is spatial grid size in the x and y directions, respectively. Numerical results are presented to support our theoretical analysis.

We develop a fully discrete weak galerkin finite element method for the initial-boundary value problem of two-dimensional sub-diffusion equation with caputo time-fractional derivative. A traditional l 1 discretization for the caputo time-fractional derivative and a weak galerkin scheme for the space integer differential operator are employed. We prove the stability of the numerical method and establish the error estimate in l 2 and discrete h 1 norms, respectively.
