"Rate optimal adaptive FEM with inexact solver for strongly monotone operators";
Talk: Mathematical Colloquium, Bielefeld (invited); 2018-06-18.

English abstract:
We consider an adaptive algorithm from Congreve & Wihler (JCAM 311, 2017) for strongly
monotone operators. The algorithm steers the local refinement of the FEM triangulation as
well as the stopping of the employed nonlinear solver. We prove that the algorithm guarantees
convergence with optimal algebraic rates. Moreover, we prove that the computational cost is

The talk is based on joint work with Gregor Gantner, Alexander Haberl, Stefan Schimanko, and Bernhard Stiftner.
