At the end of April, junior research group leader Benjamin Unger and SimTech scientists Carsten Scherer, Tobias Holicki, and Jonas Nicodemus participated in the "Energy-Based Modeling, Simulation, and Control of Complex Constrained Multiphysical Systems" conference at the Centre International de Rencontres Mathématiques (CIRM), located close to Marseille, France. Besides being a participant himself, Benjamin Unger was also a member of the Organizing Committee and gave a talk on "Surrogate models for port-Hamiltonian systems".

"As an early career scientist, it is of course an honor to organize such a conference with established senior researchers. Overall, we are very satisfied - the consistently top-class presentations were accompanied by many exciting discussions," explains Benjamin Unger.

The conference, which has already been submitted to CIRM in 2019, is an invitation-only event whose goal was to bring together different mathematical communities to identify common new research topics. A special focus was on so-called port-Hamiltonian systems, an extension of the Hamiltonian formalism to open systems. On this topic, Benjamin Unger has recently written a survey paper, which will be published soon and is available as a preprint via https://arxiv.org/abs/2201.06590.

Another goal of the workshop was to actively integrate new early career researchers into the community. Therefore, all of them had the opportunity to present their research in short talks of 5 minutes. SimTech PhD researcher Jonas Nicodemus used this opportunity and reported on his research results on learning port-Hamiltonian systems from data, which have also been submitted for peer review in a journal and are available as a preprint on ArXiv via https://arxiv.org/abs/2204.13474

Carsten Scherer, PR in the Cluster of Excellence, gave a talk on "Dissipativity-based synthesis of optimization algorithms and extremum controllers". Tobias Holicki spoke about "A Dynamic S-Procedure for Dynamic Uncertainties". The complete conference program is available at https://conferences.cirm-math.fr/2560.html.
