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…

Approximation of the Maxwell eigenvalue problem in a Least-Squares setting
Fleurianne Bertrand, Daniele Boffi, Lucia Gastaldi
We discuss the approximation of the eigensolutions associated with the Maxwell eigenvalues problem in the framework of least-squares finite elements. We write the Maxwell curl curl…

A comparison of non-matching techniques for the finite element approximation of interface problems
Daniele Boffi, Andrea Cangiani, Marco Feder +2
We perform a systematic comparison of various numerical schemes for the approximation of interface problems. We consider unfitted approaches in view of their application to possibl…
