A comparison of four- and five-point difference approximations for stabilizing the one-dimensional stationary convection-diffusion equation
Electronic transactions on numerical analysis, Tome 32 (2008), pp. 63-75
Some recently developed finite element stabilizations of convection-diffusion problems generate in 1D five-point difference schemes. Because there are only few results on fourand five-point schemes in the literature (in contrast to three-point schemes), we discuss some properties of such schemes with special emphasis on the choice of free parameters for a singularly perturbed problem to avoid oscillations.
