A conforming auxiliary space preconditioner for the mass conserving mixed stress method
Lukas Kogler, Philip L. Lederer, Joachim Schöberl
We are studying the efficient solution of the system of linear equation stemming from the mass conserving mixed stress (MCS) method discretization of the Stokes equations. To that…
Analysis of Weakly Symmetric Mixed Finite Elements for Elasticity
Philip L. Lederer, Rolf Stenberg
We consider mixed finite element methods for linear elasticity where the symmetry of the stress tensor is weakly enforced. Both an a priori and a posteriori error analysis are give…
Mixed finite elements for Bingham flow in a pipe
Tom Gustafsson, Philip L. Lederer
We consider mixed finite element approximations of viscous, plastic Bingham flow in a cylindrical pipe. A novel a priori and a posteriori error analysis is introduced which is base…
Hybridized Discontinuous Galerkin Methods for a Multiple Network Poroelasticity Model with Medical Applications
Johannes Kraus, Philip L. Lederer, Maria Lymbery +2
The quasi-static multiple network poroelastic theory (MPET) model, first introduced in the context of geomechanics, has recently found new applications in medicine. In practice, th…
A note on asymptotically exact a posteriori error estimates for mixed Laplace eigenvalue problems
Philip L. Lederer
We derive optimal and asymptotically exact a posteriori error estimates for the approximation of the Laplace eigenvalue problem. To do so, we combine two results from the literatur…
