The streamline-diffusion method for a convection--diffusion problem with a point source
The authors study a singularly perturbed convection-diffusion problem with a point source. This problem is solved by applying the streamline-diffusion finite element method to a class of Shishkin-type meshes. This approach enables the authors to prove pointwise error estimates, as well as the existence of superconvergent points for the first derivative. Numerical experiments support the abstract results contained in the paper.
