# Hausdorff Center for Mathematics

The Hausdorff Center for Mathematics (HCM), established in 2006 as the first German Cluster of Excellence in Mathematics, is a major center for mathematical research and international scientific exchange. Its spectrum ranges from pure and applied mathematics to interdisciplinary research, including theoretical economics. HCM features the Hausdorff Research Institute (HIM) with its trimester programs and the Hausdorff school for Mathematics (HSM) which is the central institution serving all early-career researchers in mathematics at Bonn: from doctoral students to advanced postdocs.

## News and Highlights

**Wolfgang Lück, professor at the Mathematical Institute of the University of Bonn and member of the Hausdorff Center for Mathematics, has been awarded the Karl Georg Christian von Staudt Prize by the Otto and Edith Haupt Foundation at the University of Erlangen-Nuremberg. The foundation honors his outstanding contributions to topology. The award ceremony will take place on June 6, 2025.**

**Don Zagier, Director emeritus of the Max Planck Institute for Mathematics in Bonn and associated member of the Hausdorff Center for Mathematics, was elected as a new member of the Accademia Nazionale dei Lincei. The Accademia dei Lincei will officially welcome its new members at a ceremony that will take place in Rome on Friday 8 November 2024.**

**Ana Caraiani, former Bonn Junior Fellow and Hausdorff Chair at the HCM and now professor of pure mathematics at the Imperial College London, has been awarded the 2025 Ruth Lyttle Satter Prize in Mathematics by the American Mathematical Society (AMS). She has been honored for contributions to arithmetic geometry and number theory: in particular, the Langlands program.**

**The University of Bonn is once again welcoming a top-notch reinforcement in the shape of mathematician professor László Végh. He has been appointed to a Hertz Chair, which connects up different disciplines at the University of Excellence in a unique way. László Végh will be based in the Transdisciplinary Research Area "Modelling”, where he will help to strengthen the links between different departments in the fields of algorithms and optimization problems in particular. In addition, László Végh is a member of the Research Institute for Discrete Mathematics and the Hausdorff Center for Mathematics (HCM).**

## Felix Hausdorff

The center is named after the famous mathematician Felix Hausdorff. Felix Hausdorff was born on 8 November 1868 in Breslau as the son of a Jewish merchant. He was appointed associate professor in Bonn in 1910 and assumed a full professorship in 1913 in Greifswald. He returned to Bonn in 1921 to continue his work until 1935. During the national socialist regime, he suffered increasing harassment and humiliation until 26 Januar 1942, when he and his wife chose suicide over imminent deportation to a concentration camp. With his masterpiece Grundzüge der Mengenlehre (1914), Hausdorff established topology as an independent discipline in mathematics. In addition, Hausdorff made significant contributions to general and descriptive set theory, measure theory, algebra, functional anaylsis, probability theory, and insurance mathematics.
