Adaptive guaranteed lower eigenvalue bounds with optimal convergence rates
Carsten Carstensen, Sophie Puttkammer
Guaranteed lower Dirichlet eigenvalue bounds (GLB) can be computed for the -th Laplace operator with a recently introduced extra-stabilized nonconforming Crouzeix-Raviart (…

How to prove the discrete reliability for nonconforming finite element methods
Carsten Carstensen, Sophie Puttkammer
Optimal convergence rates of adaptive finite element methods are well understood in terms of the axioms of adaptivity. One key ingredient is the discrete reliability of a residual-…
