Mass-lumped mixed finite elements methods and the abstract gradient scheme framework for elliptic problems

We provide a general framework for second-order elliptic problems, which includes a variety of boundary conditions. We show how one can apply mass-lumped mixed finite element to this problem, and we provide sufficient conditions for the convergence of such a method. In particular...
