"Instance-optimal goal-oriented adaptivity";
angenommen für Computational Methods in Applied Mathematics (2020).



Kurzfassung englisch:
We consider an adaptive finite element method with arbitrary but fixed
polynomial degree p >= 1, where adaptivity is driven by an edge-based residual error estimator. Based on the modified maximum criterion from [Diening et al, Found. Comput.Math. 16, 2016], we propose a goal-oriented adaptive algorithm and prove that it is instance optimal. Numerical experiments underline our theoretical findings.
