Abstract

The linear singularly perturbed convection-diffusion problem in one dimension is considered and its discretization on a Bakhvalov-type mesh generated by a smooth mesh-generating function is analyzed. The preconditioning technique is used to obtain the first-order pointwise convergence uniform in the perturbation parameter.
