Welcome

Welcome to the website of the 19th Central European Mathematical Olympiad in Chemnitz!

From 25 to 30 August 2025, Chemnitz hosted 66 young people from eleven Central European countries for the 19th Central European Mathematical Olympiad (MEMO). These outstanding mathematical talents competed in an individual contest, demonstrating their creativity in solving challenging problems, and in a team contest, where they showcased collaboration and team spirit.

Through the cultural heritage of mathematics, the participants and their mentors brought valuable impulses to the European Capital of Culture and also took the opportunity to explore Chemnitz and the Ore Mountain region with its rich culture, economy, and science.

Mathematical Olympiads have a long tradition in Chemnitz. Unforgettable were the days of May 2019, when the city became the unofficial “capital of mathematics” by hosting the national round of the 58th German Mathematical Olympiad (www.mo2019.de).

Every year, hundreds of students compete here in regional and state rounds. With MEMO, this tradition was enriched by an international atmosphere – a milestone for the city.

After the 2014 edition in Dresden, this prestigious competition was held in Germany for only the second time. The local organizing team included the Förderverein für Mathematik zu Chemnitz e.V., the City of Chemnitz, the State Office for Schools and Education, and the Johannes-Kepler-Gymnasium Chemnitz. The mathematical part of the competition was hosted at the Faculty of Mathematics of Chemnitz University of Technology.
