abstract = {<p style="text-align: justify;">We obtain improved derivative estimates for the solution of the semilinear singularly
perturbed reaction-diffusion problem in one dimension. This enables us to modify the transition
points between the fine and coarse parts of the Shishkin discretization mesh. We prove that the
numerical solution, obtained by using the central finite-difference scheme on the modified mesh,
retains the same order of convergence uniform in the perturbation parameter as on the standard
Shishkin mesh. However, the modified mesh may be denser in the layers than the standard one,
and, when this is the case, numerical results show an improvement in the accuracy of the computed
solution.</p>},
