An expanded mixed finite element simulation for two-sided time-dependent fractional diffusion problem
Abstract In this paper, we consider a time-dependent diffusion problem with two-sided Riemann-Liouville fractional derivatives. By introducing a fractional-order flux as auxiliary variable, we establish the saddle-point variational formulation, based on which we employ a locally conservative mixed f...
