Abstract
We consider the dual mixed formulation of the Dirichlet problem. We sh ow that all appropriate numerical integration allows to eliminate grad ient variable. In this fashion we explicitly get a scheme in which the only unknows are the initial ones and which can be understood as a Fi nite Volume one. Mixed Finite Element techniques can be used to obtain error estimations for some Finite Volume schemes.
