dc.description.abstract | We consider an unsteady 1D singularly perturbed convection–diffusion problem. We discretize such a problem by the linear finite element method (FEM) on a Shishkin mesh and by a discon- tinuous Galerkin method in time. We present optimal a priori error estimates for low order time discretizations. | en |
