Die Freie Universität Berlin lädt am 25. April zum 29. Tag der Berliner Mathematik ein. Schüler*innen, Lehrer*innen und alle an Zahlen interessierte Bürger*innen können dort in die Welt der Mathematik eintauchen.

Mathematical research is thrilling and beautiful—but also sometimes frustrating and overwhelming. Is getting stuck normal? Does everyone else really make constant progress? Join a candid talk with Gavril Farkas, Andrea Walther, and Alexandra Wesolek on coping with dead ends, setbacks, and the long, often lonely road in mathematical research.

In this talk, Alexei Skorobogatov will survey the local-to-global principle for rational points, also known as the Hasse principle, with a focus on surfaces. He is Professor of Pure Mathematics at Imperial College London and works in arithmetic geometry, in particular on rational points and Brauer groups.

In the last Kovalevskaya colloquium of 2025, Niethammer will give an overview of the basic properties of coagulation equations, explain some of the main challenges in its analysis and report on recent progress Barbara Niethammer is Professor at the Institute for Applied Mathematics at the University of Bonn.

In this talk, Böttcher will introduce he area of graph and hypergraph decompositions, with background, motivation, and some history, indicating how randomness and quasirandomness are instrumental for tackling these problems. Julia Böttcher is professor in Mathematics at the London School of Economics and Political Science.
