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.

Bonn Mathematics Mourns Death of Günter Harder9
The Mathematical Institute of the University of Bonn, the Hausdorff Center for Mathematics and the Max Planck Institute for Mathematics mourn the death of Günter Harder, who passed away on Tuesday, June 10, at the age of 87. Günter Harder was a professor at the Mathematical Institute of the University of Bonn for about thirty years, a member of the Hausdorff Center for Mathematics, and a scientific member of the Max Planck Institute for Mathematics since 1991 and director from 1995 to 2006. His work area was arithmetic geometry and number theory, and after his retirement he remained a very active emeritus director. We have lost a wonderful person and a great mathematician who will be deeply missed!

New Collaborative Research Center for Bonn Mathematics10
The German Research Foundation (Deutsche Forschungsgemeinschaft; DFG) approved a new Collaborative Research Center (Sonderforschungsbereich; SFB) at the University of Bonn. A team of 19 principal investigators and their working groups will study the mathematical structures underlying complex phenomena in areas of criticality. The spokesperson of the CRC is Leibniz Prize winner Professor Angkana Rüland of the Hausdorff Center for Mathematics. The Collaborative Research Center will receive nearly four years of DFG funding of approximately seven million euros.

Skolem Award for Floris van Doorn11
Together with four other scientists, Floris van Doorn receives the Thoralf Skolem Award 2025. This prize rewards a paper, published in the International Conference on Automated Deduction (CADE) proceedings ten years ago, that has passed the test of time by proving to be the most influential paper in the field of automated deduction in that year. The award will be presented at CADE-30 in July 2025.

Hausdorff Chairs

The Hausdorff Chairs make it possible to complement the faculty without the usual constraints in terms of timing and fields. We seek internationally outstanding scientists who fit into the broad spectrum of the Hausdorff Center.

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.
