Space-time FEM-BEM couplings for parabolic transmission problems
Thomas Führer, Gregor Gantner, Michael Karkulik
We develop couplings of a recent space-time first-order system least-squares (FOSLS) method for parabolic problems and space-time boundary element methods (BEM) for the heat equati…

Tensor finite elements for smectic liquid crystals
Thomas Führer, Norbert Heuer, Torsten LinÃ
We present a tensor-based finite element scheme for a smectic-A liquid crystal model. We propose a simple Céa-type finite element projection in the linear case and prove its quasi…

Mixed finite elements for Kirchhoff-Love plate bending
Thomas Führer, Norbert Heuer
We present a mixed finite element method with triangular and parallelogram meshes for the Kirchhoff-Love plate bending model. Critical ingredient is the construction of low-dimensi…
