Abstract
We analyze the stabilizing effect of the introduction of suitable bubble functions in DG formulations for linear second order elliptic problems, working, for the sake of simplicity, on Laplace operator. In particular we find that the addition of a single bubble per element can stabilize the nonsymmetric formulation of Baumann-OdenFile in questo prodotto:
