Hausdorff Center for Mathematics

Events Calendar of Bonn 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.

Henning Heller receives the Montucla Prize

Henning Heller, postdoctoral researcher at the Mathematical Institute of the University of Bonn and associate member of the Hausdorff Center for Mathematikcs, receives the prestigious Montucla Prize from the International Commission for the History of Mathematics (ICHM) 2025. The ICHM is composed of representatives from around 55 nations in which the history of mathematics is taught and/or actively researched. The Montucla Prize is awarded every four years to the author of the best article by a early career scholar published in Historia Mathematica in the four years preceding the International Congress of History of Science and Technology.

Bonn again second best university at IMC

At this year's International Mathematics Competition for University Students (IMC) in Blagoevgrad (Bulgaria), held from July 28 to August 3, 2025, the Bonn team finished second in the unofficial team ranking and was thus - as last year - the second most successful university in the world in the competition behind St. Petersburg State University.

Frontiers of Science Award for Christian Brennecke

For his scientific work “Bogoliubov Theory in the Gross-Pitaevskii Limit”, Christian Brennecke, Bonn Junior Fellow at the HCM and Professor at the Institute for Applied Mathematics, University of Bonn, received the Frontiers of Science Award 2025, together with three co-authors. The prize was awarded on July 13 at the International Congress of Basic Science in Beijing.

Jan Schröer, Lorenzo Portinale, Thoralf Räsch: Three teaching awards for Bonn Mathematics

The University of Bonn has honored 14 lecturers for their outstanding commitment with teaching awards, including Jan Schröer from the Mathematical Institute. The prizewinners were selected by the students themselves. The ceremonial presentation of certificates by the Vice-Rector for Studies, Teaching and University Development, Klaus Sandmann, took place as part of the Bonn University Festival in front of over 7,000 participants on Bonn's Hofgartenwiese. In addition, further teaching awards from the Faculty of Mathematics and Natural Sciences were presented by Vice Dean Barbara Kirchner as part of the Faculty's academic ceremony. Lorenzo Portinale from the Institute of Applied Mathematics and Thoralf Räsch from the Institute of Mathematics are among the awardees for 2025. Bonn Mathematics would like to congratulate all three prizewinners!

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.
