In this talk, we focus on understanding the problem of ranking from both an informational perspective – characterising the fundamental statistical thresholds for optimal estimation – and a computational one – characterising the fundamental limits of computationally efficient estimation. A core question for these problems is whether statistical optimality is compatible with computational efficiency...

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 der Vortragsreihe MATHINSIDE geben Wissenschaftler*innen des Exzellenzclusters MATH+ spannende Einblicke in ihre Forschungsarbeit und in die Anwendungsgebiete der Mathematik. Das Vortragsprogramm eignet sich hervorragend als Ausflugsziel für Schulklassen und -kurse ab Klassenstufe 10.

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.
