An augmented mixed finite element method with Lagrange multipliers: A priori and a posteriori error analyses
In this paper, we provide a priori and a posteriori error analyses of an augmented mixed finite element method with Lagrange multipliers applied to elliptic equations in divergence form with mixed boundary conditions. The ...
An adaptive stabilized finite element scheme for a water quality model
Residual type a posteriori error estimators are introduced in this paper for an advection–diffusion–reaction problem with a Dirac delta source term. The error is measured in an adequately weighted W1,pW1,p-norm. These ...
Error estimators for advection–reaction–diffusion equations based on the solution of local problems
This paper deals with a posteriori error estimates for advection–reaction–diffusion equations. In particular, error estimators based on the solution of local problems are derived for a stabilized finite element method. ...
