## a b s t r a c t In this paper, we propose a posteriori error estimators for certain quantities of interest for a first-order least-squares finite element method. In particular, we propose an a posteriori error estimator for when one is interested in ฯƒ -ฯƒ h 0 where ฯƒ = -Aโˆ‡u. Our a posteriori err
