Investigation of some transmission problems with sign-changing coefficients. ...
In this thesis, we study various operators that present a sign-changing in their principal part. These operators appear in particular in electromagnetism when studying... -
T-coercivity: application to the discretization of Helmholtz-like problems
To solve variational indefinite problems, a celebrated tool is the Banach-Nečas- Babuška theory, which relies on the inf-sup condition. Here, we choose an alternate... -
T-coercivity and continuous Galerkin methods: application to transmission pro...
To solve variational indefinite problems, one uses classically the Banach-Necas-Babuška theory. Here, we study an alternate theory to solve those problems:... -
