Adaptive Crouzeix-Raviart Boundary Element Method
Norbert Heuer, Michael Karkulik
For the non-conforming Crouzeix-Raviart boundary elements from [Heuer, Sayas: Crouzeix-Raviart boundary elements, Numer. Math. 112, 2009], we develop and analyze a posteriori error…
L2-orthogonal projections onto finite elements on locally refined meshes are H1-stable
Michael Karkulik, Carl-Martin Pfeiler, Dirk Praetorius
We merge and extend recent results which prove the H1-stability of the L2-orthogonal projection onto standard finite element spaces, provided that the underlying simplicial triangu…
ZZ-type aposteriori error estimators for adaptive boundary element methods on a curve
Michael Feischl, Thomas Führer, Michael Karkulik +1
In the context of the adaptive finite element method (FEM), ZZ-error estimators named after Zienkiewicz and Zhu are mathematically well-established and widely used in practice. In…
