Provides rigorous error control for conforming mixed approximations, but the contribution is incremental as it extends existing functional a posteriori techniques to a specific class of PDEs.
The authors derive functional a posteriori error equalities and constant-free two-sided estimates for coercive problems with lower order terms, measuring error in a combined primal-dual norm.
We derive functional a posteriori error equalities and constant free two sided estimates for certain types of partial differential equations. The error is measured in a combined norm which takes into account both the primal and dual variable.
