Functional A Posteriori Error Control for Conforming Mixed Approximations of Coercive Problems with Lower Order Terms
arXiv:1512.08462
Abstract
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.
