Robust a posteriori error bounds for spline collocation applied to singularly perturbed reaction-diffusion problems

Torsten Linß and Goran Radojev

Abstract

Collocation with arbitrary order $C^1$-splines for a singularly perturbed reaction-diffusion problem in one dimension is studied. Robust a posteriori error bounds are derived for the collocation method on arbitrary meshes. These bounds are used to drive an adaptive mesh moving algorithm. Numerical results are presented.
