Finite element approximation for time-dependent diffusion with measure-valued source
The convergence of finite element methods for elliptic and parabolic partial differential equations is well-established if source terms are sufficiently smooth. Noting prove new convergence order results in two and three dimensions ...

On the Stability in the Finite Element Solution of the Navier-Stokes Equations for Incompressible Flows
We consider the Navier-Stokes equations for the incompressible fluid flow. In the paper we first discuss the concept of stability for an elliptic problem. Then we consider the Stokes problem. Stability is then dicussed for the advec...

Equivalence between lowest-order mixed finite element and multi-point finite volume methods. Derivation, properties, and numerical experiments
We consider the lowest-order Raviart--Thomas mixed finite element method for elliptic diffusion problems on simplicial meshes in two or three space dimensions. This method produces saddle-point problems for scalar and flux unknowns....
