Quasi-optimal nonconforming methods for symmetric elliptic problems. III -- DG and other interior penalty methods
Andreas Veeser, Pietro Zanotti
We devise new variants of the following nonconforming finite element methods: DG methods of fixed arbitrary order for the Poisson problem, the Crouzeix-Raviart interior penalty met…

Quasi-optimal nonconforming methods for symmetric elliptic problems. II -- Overconsistency and classical nonconforming elements
Andreas Veeser, Pietro Zanotti
We devise variants of classical nonconforming methods for symmetric elliptic problems. These variants differ from the original ones only by transforming discrete test functions int…

Quasi-optimal nonconforming methods for symmetric elliptic problems. I -- Abstract theory
Andreas Veeser, Pietro Zanotti
We consider nonconforming methods for symmetric elliptic problems and characterize their quasi-optimality in terms of suitable notions of stability and consistency. The quasi-optim…
