AB - <p style="text-align: justify;">In this paper, a bilinear Streamline-Diffusion finite element method on
Bakhvalov-Shishkin mesh for singularly perturbed convection-diffusion problem
is analyzed. The method is shown to be convergent uniformly in the perturbation
parameter $ϵ$ provided only that $ϵ ≤ N^{−1}$. An&nbsp;$\mathcal{O}(N^{−2}$(ln$N$)$^{1/2}$) convergent rate in
a discrete streamline-diffusion norm is established under certain regularity assumptions. Finally, through numerical experiments, we verified the theoretical results.</p>
