Abstract
This study documents the development of a novel scheme for spatial discretization of the time-fractional Sobolev equation. The scheme is based on a combination of continuous and discontinuous Galerkin methods which is called the enriched Galerkin method. The enriched Galerkin method has more degrees of freedom than the continuous Galerkin but smaller than the discontinuous Galerkin method. Also, the Caputo-type fractional operator is considered for fractional-order derivatives. Furthermore, unconditionally stability of the method is proved and a priori error estimate for the approximation is presented. Finally, we present several numerical examples to confirm the analytical results.
