A posteriori error estimate for the mixed finite element method. (English) Zbl 0864.65068

Summary: A computable error bound for mixed finite element methods is established in the model case of the Poisson problem to control the error in the \(H (\text{div}, \Omega) \times L^2 (\Omega)\)-norm. The reliable and efficient a posteriori error estimate applies, e.g., to Raviart-Thomas, Brezzi-Douglas-Marini, and Brezzi-Douglas-Fortin-Marini elements.
