Abstract
AbstractA posteriori error estimates have had a major impact on adaptive error control for the finite element method. In this paper, we review a relatively new approach to a posteriori error estimation based on residuals and a variational analysis. This approach is distinguished by a direct attempt to account for the effects of stability on the propagation of error. We illustrate properties of this approach using several examples.
