摘要
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(div,Omega) xL(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.
