27 November – Mario Kummer: Fourier Quasicrystals

Quasicrystals were discovered in the 1980s and have led to a paradigm change in crystallography. Their existence shows that order can exist without regular repetition. They scatter X-rays into patterns with sharp peaks, much like ordinary crystals. Yet the mathematics behind this picture holds a

6 November – Silvia De Toffoli: Mathematics After AI

OpenAI’s announcement of an AI-generated solution to the Navier–Stokes problem has intensified speculation that mathematics might soon be “solved,” as many have said that chess and Go have been “solved.” In this talk, I challenge this narrative by questioning two assumptions on which it rests:

9. Oktober – Mathenacht aus Berlin, Bonn und Münster

Am 9. Oktober heißt es wieder: Einschalten zur „Mathenacht aus Berlin, Bonn und Münster“! Wissenschaftler*innen der Exzellenzcluster MATH+ (Berlin), Hausdorff Center for Mathematics (Bonn) und Mathematik Münster zeigen online in Workshops für Kinder und Jugendliche, einer Talkrunde zu "KI und die Zukunft der Mathematik" sowie

26 June – Emanuel Milman: Multi-Bubble Isoperimetric Problems

The classical isoperimetric inequality in Euclidean space Rⁿ states that among all sets of prescribed volume, the Euclidean ball (uniquely) minimizes surface area, explaining why a single soap bubble is always a round sphere. One may similarly consider isoperimetric problems in more general spaces, such
