abstractNote={Abstract
A singularly perturbed two-point boundary-value problem is considered.
Working in the discrete maximum norm, a necessary condition for the
convergence (uniformly in the singular perturbation parameter) of general
difference schemes on general meshes is proved. This encompasses both a 1976
result of Miller for uniform meshes and more recent results of the same
author that deal with piecewise uniform Shishkin meshes.},
