We consider the finite element approximation of the boundary value problem where f2 is a two-or three-dimensional polyhedral domain and A(u) is a Lipschitz continuous function satisfying A(u)>~6>O. Under the assumption of the uniqueness of the weak solution, we can show the L °’ convergence of the

In this article, a novel dual-primal mixed formulation for second-order elliptic problems is proposed and analyzed. The Poisson model problem is considered for simplicity. The method is a Petrov-Galerkin mixed formulation, which arises from the one-element formulation of the problem and uses trial f

We consider saddle-point problems that typically arise from the mixed finite element discretization of secondorder elliptic problems. By proper equivalent algebraic operations the considered saddle-point problem is transformed to another saddle-point problem. The resulting problem can then be effici
