Query: Supercloseness of the SDFEM on Shishkin triangular meshes for problems
  with exponential layers   In this paper, we analyze the supercloseness property of the streamline
diffusion finite element method (SDFEM) on Shishkin triangular meshes, which is
different from one in the case of rectangular meshes. The analysis depends on
integral inequalities for the part related to the diffusion in the bilinear
form. Moreover, our result allows the construction of a simple postprocessing
that yields a more accurate solution. Finally, numerical experiments support
these theoretical results.
