Abstract

Error estimates of finite element methods for reaction-diffusion problems are often realized in the related energy norm. In the singularly perturbed case, however, this norm is not adequate. A different scaling of the H 1 seminorm leads to a balanced norm which reflects the layer behavior correctly. We discuss anisotropic problems, semilinear equations, supercloseness and a combination technique. Moreover, we consider different classes of layer-adapted meshes and sketch the three-dimensional case. Remarks to systems and problems with different layers close the paper.
