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.

"Hot Topics" Conference on "Quantum Topology", May 12 - 16, 2025

The discovery of polynomial invariants of knots by Jones sparked the study of quantum topology in the late 80s and 90s. Work over the last two decades has led to deeper understanding of the mathematical structures behind these invariants.

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.

Location: 
MPIM Lecture Hall
Parent event: 
Oberseminar Arithmetic Geometry and Representation Theory

We formulate a new version of the local Langlands correspondence for discrete L-parameters which involves (Weyl orbits of) packets of representations of all twisted Levi subgroups of a connected reductive group G through which a given parameter factors and prove that this version of the correspondence is true if one assumes the pre-existing local Langlands conjectures.

Topological Aspects in Representation Theory of 2-Graded 2-Groups

Location: 
MPIM Seminar Room
Parent event: 
Abstract Homotopy Theory Seminar

A 2-graded group is a pair: a group G and its index two subgroup H (even elements). A 2-graded 2-group is a 2-group GG such that the fundamental group $\pi_1(GG)$ is 2-graded.
They have several representation theories: 4 for groups, at least 8 for 2-groups. The interplay between them have interesting topological aspects that I will discuss in my talk.

The talk is based on the same recent works with James Taylor (Oxford) and Matthew B. Young (Utah State), as my November talk at the Representation Theory Oberseminar. 

The Cohen–Lenstra moments for functions fields and stable homology of Hurwitz spaces

Parent event: 
MPIM Topology Seminar

The Cohen--Lenstra heuristics predict the distribution of the odd part of class groups of quadratic fields, and are one of the driving conjectures in arithmetic statistics. I will explain work with Aaron Landesman, where we compute the moments of the Cohen--Lenstra distribution for function fields, when the size of the finite field is sufficiently large (depending on the moment).

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.

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.
