Abstract
In this paper, time fractional reaction–diffusion equations with the Caputo fractional derivative are solved by using the classical -formula and the finite volume element (FVE) methods on triangular grids. The existence and uniqueness for the fully discrete FVE scheme are given. The stability results and optimal a priori error estimate in -norm are derived, but it is difficult to obtain the corresponding results in -norm, so another analysis technique is introduced and used to achieve our goal. Finally, some numerical results are given to verify the feasibility and effectiveness.
