Axioms of Adaptivity with Separate Marking for Data Resolution

Mixed finite element methods with flux errors in H(div)-norms and div-least-squares finite element methods require a separate marking strategy in obligatory adaptive mesh-refining. The refinement indicator σ2(T ,K) = η2(T ,K) + μ2(K) of a finite element domain K in an admissible triangulation T consists of some residual-based error estimator η(T ,K) with… (More)
