On the stabilization of a virtual element method for an acoustic vibration problem
Linda Alzaben, Daniele Boffi, Andreas Dedner +1
In this paper we introduce an abstract setting for the convergence analysis of the virtual element approximation of an acoustic vibration problem. We discuss the effect of the stab…

On the spectrum of the finite element approximation of a three field formulation for linear elasticity
Linda Alzaben, Daniele Boffi
We continue the investigation on the spectrum of operators arising from the discretization of partial differential equations. In this paper we consider a three field formulation re…

On the spectrum of an operator associated with least-squares finite elements for linear elasticity
Linda Alzaben, Fleurianne Bertrand, Daniele Boffi
In this paper we provide some more details on the numerical analysis and we present some enlightening numerical results related to the spectrum of a finite element least-squares ap…
