Seminar: Current Topics in Approximation Theory (SoSe 2024)

Prof. Dr. Markus Bachmayr


In this seminar, we discuss recent research in approximation theory and related numerical methods. In this semester, we focus in particular on different notions of widths of compact sets and their applications in the analysis of nonlinear approximation methods.


If you are interested in participating in the seminar, please contact Prof. Bachmayr directly. Registration is via RWTHonline. If you register for the seminar you will automatically get access to the course room in RWTHmoodle.
