Conference on "Asymptotic Counting and L-Functions", May 5 - 9, 2025

Many interesting arithmetic functions such as class numbers, Fourier coefficients of modular forms, have a rather varying behavior that is only partially understood. However, often it is possible to determine some (possibly weighted) average for them. The approach is often to associate an L-series to the arithmetic quantity of interest and study whether this has an analytic continuation, study the location of its zeros and poles.

Twinned workshop on "Quantum Field Theory and Topological Phases via Homotopy Theory and Operator Algebras", June 30 - July 11, 2025

Quantum Field Theory (QFT) and Quantum Statistical Mechanics are central to high energy physics and condensed matter physics; they also raise deep questions in mathematics.  The application of operator algebras to these areas of physics is well-known. Recent developments indicate that to understand some aspects QFT properly a further ingredient is needed: homotopy theory and infinity-categories.

Conference on "Progress and Emergent Theories in Zeta and L-Functions" (PRETZL), July 21-25, 2025

There has been an enormous amount of progress in the analytic theory of zeta and L-functions over the past decade. Our understanding in the classical theory of the value distribution of the Riemann zeta function has achieved new heights with spectacular breakthroughs on moments and extreme values (both local and global) leading to a better understanding of families of L-functions more generally.

Conference in Memory of Yuri Manin, August 11 - 15, 2025

Yuri I. Manin (February 16, 1937 - January 7, 2023) was an extraordinary figure in mathematics. Renowned for his creativity, Professor Manin's profound insights -- in diverse subjects ranging from algebraic geometry to mathematical physics and quantum computing -- helped shape modern mathematics. Professor Manin was Director of the Max Planck Institute for Mathematics in Bonn. In this week-long conference, the institute will honor his results and ideas and will attempt to trace some of their developments.

Abstract Homotopy Theory Seminar

A classical theorem of Tierney characterizes abelian categories as those additive categories which satisfy a further purely nonadditive property known as Barr exactness. In this talk I will explain a version of this result in the setting of higher category theory: an infinity category is Barr exact and additive if and only if it arises as the connective half of a t-structure on some stable infinity category.

Let $\alpha$ be a real number greater than one and $\beta$ a positive real number. We prove that $\left(\zeta(\alpha + \beta n)\right)_{n\in\mathbb{N}}$ arise as moments of a positive definite Borel measure and construct the corresponding matrix theory. We determine its asymptotic behavior and show its relation to Euler-MacLaurin summation.

Mathematical formalization is the process of digitizing mathematical definitions and results using a "proof assistant", a computer program capable of checking logical statements against a set of inference rules and some basic axioms. In recent years, the community of mathematicians working on formalization has grown rapidly and has reached milestones that demonstrate the ability to formalize results at the frontier of knowledge. Proof assistants have applications to mathematical research, teaching, and communication.

Bounds for Kloosterman Sums for $\mathrm{GL}_n$

Classical Kloosterman sums defined by $S(m,n;c):=\sum_{x\in (\mathbb{Z}/c\mathbb{Z})^*}e\Big(\frac{mx+n\overline{x}}{c}\Big)$ for $m,n\in\mathbb{Z}$ and $c\in\mathbb{Z}^+$ have become ubiquitous in Number Theory appearing for example in Fourier coefficients of classical Poincaré series and therefore in the geometric side of relative trace formulae of Petersson-Kuznetsov type.
Working with relative trace formulae over $\mathrm{GL}_n$ requires understanding of more general Kloosterman sums.
