Project Description The computer-aided control system design for nonlinear large-dimensional systems is a tremendous task as it has to cope both with model complexities due to nonlinear dynamics and with computational challenges that are caused by the system’s size.
The one mathematics directed and driven consortium in the NFDI. Our institute has been a co-applicant and we are co-managing (together with WWU Münster) the part on Scientific Computing (Task Area 2 in MaRDI).
The research training group MathCoRe at that OVGU provides a both challenging and supporting environment for a small community of graduate students to pursue a PhD in a field that relates to mathematical complexity reduction.

An update to my 2020 talk and takes on the DEAL.
The computation of controller gains for the (linearization based) $H_\infty$ robust control of linear (and nonlinear) dynamical systems amounts to the solution of indefinite Riccati equations. For large-scale systems, a direct approach is infeasible because of both computational efforts and memory requirements.
Für SchülerUnis bietet sich die Modellierung von Epidemien an, weil die Mechanismen und die Mathematik im Modell nachvollziehbar sind. Bisher hatte mich an meinen Versuchen damit aber gestört, dass das Thema etwas trübe ist (niemand hat Lust auf Corona oder einen Zombie) Es doch abstrakte Mathe bleibt (wenn beispielsweise im deterministischen “SIR”-Modell die Ansteckungsraten einfach angenommen werden) und letztlich die Verbindung zwischen Modell und Person nicht hergestellt wird.
How to approximate general nonlinear systems by parameter dependent linear system using deep neural networks.
While things were shifting away from away from keyboard, I found little pleasures in seeing software tools in production. Most of all I enjoy small scripts1 that take a few lines of readable text and turn it into a website for an online course, into lecture notes, or a slide deck for presentation.
