# Hausdorff Center for Mathematics

Bonn is an internationally renowned center for mathematical research and teaching. 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, the Hausdorff school (HSM) which mainly addresses postdocs, and our graduate school (BIGS) for PhD students.

## News and Highlights

**Once a year, the Bonn Mathematical Society (Bonner Mathematische Gesellschaft, BMG) awards a prize for outstanding Bachelor's theses in mathematics.**

**Students who have completed their Bachelor's degree by September 30 of the respective year will be considered. Two to three prizes for graduates of a mathematics bachelor's degree (including one female) and one for a graduate of the Bachelor's degree in mathematics education are awarded. The prize consists of a certificate and a monetary prize.**

**They are the best young German female mathematicians: At the European Girls' Mathematical Olympiad 2024 (EGMO) in Tskaltubo (Georgia), the German team won one gold and two silver medals. A total of 212 young people from 54 countries took part in the top international tournament for mathematically talented school girls. As every year, the German team was supported by the HCM and assisted on site by female PhD students from Bonn.**

**Many kidney diseases are manifested by protein in the urine. However, until now it was not possible to determine whether the protein excretion is caused by only a few, but severely damaged, or by many moderately damaged of the millions of small kidney filters, known as glomeruli. Researchers at the University Hospital Bonn, in cooperation with mathematicians from the University of Bonn, have developed a new computer method to clarify this question experimentally. The results of their work have now been published as an article in press in the leading kidney research journal "Kidney International".**

**The Carl Friedrich von Siemens Foundation awards the Heinz Gumin Prize for Mathematics to Don Zagier, Director Emeritus at the Max Planck Institute for Mathematics in Bonn and Associate Member of the Hausdorff Center for Mathematics. The Foundation hereby honors the prizewinner's groundbreaking research work on number theory and the theory of modular forms. At 50,000 euros, the Gumin Prize is the most highly endowed mathematics prize in Germany. The award ceremony will take place in mid-May 2024 at the Carl Friedrich von Siemens Foundation.**

## 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.
