This traditional conference of Chemnitz University of Technology was organized in collaboration with Professor Arnd Rösch's Nonlinear Optimization Working Group and took place from September 15 to 17, 2025, at the Katholische Akademie Die Wolfsburg in Mülheim an der Ruhr.

Inverse problems and their applications are being researched by Dr. Yi-Hsuan Lin from the National Yang Ming Chiao Tung University (Taiwan). He is a guest of Prof. Dr. Irwin Yousept in the Department of Mathematics for 18 months. Lin's stay is funded by a research fellowship for experienced researchers in the Humboldt Foundation’s Henriette Herz Scouting Program.

Making cars less accident prone, more efficient as well as aerodynamic - all this can be facilitated by mathematics.
Prof. Dr. Antoine Laurain is developing mathematical pathways with the help of which mobile units can be designed more environmentally friendly as well.
He holds a professorship for Infinite-Dimensional Optimization at the Faculty of Mathematics at the University of Duisburg-Essen.

From March 7 to 10, 2023, the University of Duisburg-Essen hosts the German Probability and Statistics Days. The Stochastics Group of our department is significantly involved in the organisation of this big event.

As of May 1, 2021, Dr. Johannes Sprang has started as a junior professor in the Department of Mathematics at Essen. His research focuses on arithmetic geometry and number theory. Before coming to Essen he worked at the University of Regensburg. We are very happy to welcome him in our faculty.

With great dismay the Faculty of Mathematics learned of the death of its esteemed colleague Prof. Dr. Dr. h. c. Heinrich Wefelscheid. Shortly after his 79th birthday he passed away unexpectedly for many of us.
