Flux Recovery and A Posteriori Error Estimators: Conforming Elements for Scalar Elliptic Equations

In this paper, we first study two flux recovery procedures for the conforming finite element approximation to general second-order elliptic partial differential equations. One is accurate in a weighted L2 norm studied in [Z. Cai and S. Zhang, SIAM J. Numer. Anal., 47 (2009), pp. 2132
