S4E2 – Convergence and Optimality of Adaptive Finite Element Methods
Assistent: Philipp Morgenstern
Requirements: Basic knowledge in partial differential equations and finite element methods.
Self-adaptive discretization methods for the numerical solution of partial differential equations have gained enormous importance in many scientific and engineering applications. These methods aim to minimize the amount of work that is required to obtain a numerical solution within a prescribed tolerance. Their driving force are posteriori error estimators which are used to control the adaptive mesh refinement or, in general, the adaptive enrichment of finite element spaces.
This seminar concerns the recent algorithmic and theoretical breakthroughs in this context, this is, the convergence and optimality of adaptive finite element methods in the sense of quasi-minimal computational complexity.
The seminar will be based mainly on selected journal articles. Students interested in the seminar might contact P. Morgenstern in advance to register.
