AB - <p style="text-align: justify;">A parabolic initial-boundary value problem with solutions displaying
exponential layers is solved using layer-adapted meshes. The paper combines
finite elements in space, i.e., a pure Galerkin technique on a Shishkin
mesh, with some standard discretizations in time. We prove error estimates as
well for the $\theta$-scheme as for discontinuous Galerkin in time.</p>
