In this paper we present a residual-based a posteriori error estimate of a natural mesh dependent energy norm of the error in a family of discontinuous Galerkin approximations of elliptic problems. The theory is developed for an elliptic model problem in two and three spatial dimensions and general

A posterior% error estimates are derived for a stabilized discontinuous Galerkin method (DGM) [l]. Equivalence between the error norm and the norm of the residual functional is proved, and consequently, global error estimates are obtained by estimating the norm of the residual. Oneand two-dimensiona
## a b s t r a c t In this paper, two reliable and efficient a posteriori error estimators for the Bubble Stabilized Discontinuous Galerkin (BSDG) method for diffusion-reaction problems in two and three dimensions are derived. The theory is followed by some numerical illustrations.
## Abstract In this article, we develop functional a posteriori error estimates for discontinuous Galerkin (DG) approximations of elliptic boundaryβvalue problems. These estimates are based on a certain projection of DG approximations to the respective energy space and functional a posteriori estim
