Quiz-Fans und Science-Enthusiast*innen aufgepasst! Auch 2026 laden die Berliner Exzellenzcluster wieder zum „Exzellenten Pub Quiz“ bei der „Langen Nacht der Wissenschaften“ ein – mit spannenden, lustigen und überraschenden Fragen aus ihren vielfältigen Forschungsbereichen. Stellt ein Team (2–4 Personen) mit kreativem Teamnamen zusammen, diskutiert und rätselt mit!

In this talk, Jessica Fintzen will introduce p-adic numbers and p-adic groups and then provide an overview of what we know about the representations of these groups including recent developments. This means she will explain how close we are to answering the key question above. She might also sketch applications to other questions in mathematics.

In this talk (Kovalevskaya Colloquium), Victoria Hoskins will introduce moduli of representations of quivers and outline some connections with representation theory, before explaining recent progress for quivers with multiplicities and highlighting various interesting open problems. This is based on joint work with E. Hamilton, J. Jackson and T. Vernet.

The Crelle journal, founded in 1826, has been closely linked to the University of Berlin and the Berlin Academy of Sciences and Humanities. The conference will focus on recent development of prominent moduli spaces in mathematics, starting from moduli space of curves, introduced by Bernhard Riemann in 1857 in his paper "Theorie der Abelschen Functionen," published in Crelle's journal.

In this talk, Hermiller will discuss three conjectures, each aimed at simplifying the task of computing unknotting numbers. She will describe how her resolution of one of these conjectures several years ago, in joint work with Mark Brittenham, led them recently to resolve another – the (non)additivity of unknotting number under connected sum.

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...
