• Abstract

Error estimates of finite element methods for reaction-diffusion problems are often realised in the related energy norm. In the singularly perturbed case, however, this norm is not adequate. A different scaling of the $H$$m seminorm for 2m-th order problems leads to a balanced norm which reflects the layer behaviour correctly. We prove error estimates in such balanced norms and improve thereby existing estimates known in literature. • Keywords Balanced norms, reaction-diffusion problems, finite element methods. • AMS Subject Headings • Copyright COPYRIGHT: © Global Science Press • Email address • BibTex • RIS • TXT @Article{IJNAM-17-532, author = {Franz , Sebastian and Roos , Hans-G.}, title = {Error Estimates in Balanced Norms of Finite Element Methods for Higher Order Reaction-Diffusion problems}, journal = {International Journal of Numerical Analysis and Modeling}, year = {2020}, volume = {17}, number = {4}, pages = {532--542}, abstract = { Error estimates of finite element methods for reaction-diffusion problems are often realised in the related energy norm.

Error estimates of finite element methods for reaction-diffusion problems are often realised in the related energy norm. In the singularly perturbed case, however, this norm is not adequate. A different scaling of the $H$$m$ seminorm for 2$m$-th order problems leads to a balanced norm which reflects the layer behaviour correctly. We prove error estimates in such balanced norms and improve thereby existing estimates known in literature.
