Superconvergence of a finite element method for the time-fractional diffusion equation with a time-space dependent diffusivity
Abstract In this work, a time-fractional diffusion problem with a time-space dependent diffusivity is considered. The solution of such a problem has a weak singularity at the initial time t = 0 $t=0$ . Based on the L1 scheme in time on a graded mesh and the conforming finite element method in space...
