[Méthodes de Galerkine centrées aux mailles]
Dans cette Note, on propose une nouvelle approche pour obtenir et analyser des méthodes d'ordre bas pour les problèmes diffusifs. L'analyse permet d'estimer à la fois le taux de convergence et de prouver la convergence vers des solutions à régularité minimale. Cette approche combine les avancées récentes dans les méthodes de Volumes Finis et de Galerkine discontinues.
In this Note we propose a new approach to obtain and analyze lowest order methods for diffusive problems yielding at the same time convergence rates and convergence to minimal regularity solutions. The approach merges ideas from Finite Volume and discontinuous Galerkin methods.
