The Bonn Bonn Mathematical Society (Bonner Mathematische Gesellschaft, BMG) supports and promotes mathematics at the University of Bonn, for example by organizing events, awarding prizes for outstanding bachelor theses. or by supporting the mathematical institute library. Every year, the Bonn Mathematical Society organizes an entertaining event, usually on the evening before Corpus Christi.

Purpose of the BMG

The Bonn Mathematical Society (BMG) is a registered association based in Bonn, which has set itself the task of promoting mathematics in and around Bonn. Specifically, the BMG pursues the following goals:

  • Early career support: The BMG awards annual prizes for outstanding bachelor's theses in mathematics, both for graduates of a mathematics bachelor's degree and graduates of a mathematics education degree. In addition, the BMG supports Bonn Mathematics school activities in and around Bonn.
  • Outreach: The BMG organizes an entertaining evening event related to mathematics every year, for example a "Valsche Vorträge Vestival" in 2022 and a "Circus Mathematicus" in 2023.
  • Support for the library: A well-equipped and up-to-date mathematics library is essential for mathematical research and teaching. The BMG therefore sees it as its duty to support the mathematics library financially.


Every year, the BMG organizes an entertaining mathematics-related event on the evening of Corpus Christi. In the past two years, a Valsche Vorträge Vestival (2022) and a Circus Mathematicus (2023) were organized.

Circus Mathematicus

In June 2023, BMG organized a Circus Mathematicus, an entertaining event with mathematical and acrobatic contributions by DorFuchs and Albrecht Beutelspacher, among others.

Valsche Vorträge Vestival

In June 2022, the BMG organized a Valsche Vorträge Vestival, at which the speakers deliberately misled the audience with entertaining false mathematical arguments.

Bachelor prizes

Once a year, the 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.

The following students were awarded a bachelor's prize for outstanding achievements in the 2022/23 academic year:

  • Thesis title: Summen von drei quadratvollen Zahlen
  • Advisor: Prof. Dr. Valentin Blomer
  • Thesis title: Single-Source Unsplittable-Flow
  • Advisor: Prof. Dr. Vera Traub
  • Thesis title: Optimale polynomielle Approximation der Brownschen Bewegung
  • Advisor: Prof. Dr. Andreas Eberle
  • Thesis title: Magische Quadrate und Palindrome – Hinter der mathematischen Kulisse der Zauberei aus dem Buch von Ehrhard Behrends am Beispiel von ausgewählten Kapiteln
  • Advisor: Dr. Thoralf Räsch
