On numerical solution of semilinear singular perturbation problems by using the Hermite scheme


Relja Vulanović




The semilinear singularly perturbed boundary value problem is solved numerically by a finite-difference method which uses a combination of the Hermite scheme and the standard central scheme on a special non-equidistant mesh. The method is a modification of that given in [6]. We prove the same result (fourth order accuracy uniform in the perturbation parameter), but without the constraint on the nonlinearity which was used in [6].
