Nitsche's prescription of Dirichlet conditions in the finite element approximation of Maxwell's problem
D. Boffi, R. Codina, Ö. Türk
In this paper we consider the finite element approximation of Maxwell's problem and analyse the prescription of essential boundary conditions in a weak sense using Nitsche's method…

Finite element formulations for Maxwell's eigenvalue problem using continuous Lagrangian interpolations
Daniele Boffi, Ramon Codina, Önder Türk
We consider nodal-based Lagrangian interpolations for the finite element approximation of the Maxwell eigenvalue problem. The first approach introduced is a standard Galerkin metho…

A stabilized finite element method for the two-field and three-field Stokes eigenvalue problems
Önder Türk, Daniele Boffi, Ramon Codina
In this paper, the stabilized finite element approximation of the Stokes eigenvalue problems is considered for both the two-field (displacement-pressure) and the three-field (stres…
