In this paper, the finite element approximation of the Signorini problem is studied by using Lagrange multiplier methods with piecewise constant elements. Optimal ...

The pseudostress-velocity formulation of the stationary Stokes problem allows a Raviart-Thomas mixed finite element formulation with quasi-optimal convergence and ...

MICRO-DIFFUSION analysis represents a real advance in modern analytical technique. It seems strange, in fact, that the underlying principle of allowing the gaseous product of a reaction to diffuse, in ...
