MPI-Oberseminar

Posted in
Organiser(s): 
C. Kaiser
Date: 
Thu, 31/01/2013 - 15:00 - Thu, 31/12/2026 - 16:00
Location: 
MPIM Lecture Hall

The Oberseminar is a very long running seminar at MPI (‘Ober‘ standing for 'upper'). Its idea is that the guests of the MPI speak in this seminar (hopefully early in their stay) and get the chance to explain their work to the other guests.

Friedrich Hirzebruch Lecture

Posted in
Location: 
University Club Bonn

The annual Friedrich Hirzebruch Lecture is a series of lectures started in 2007 on the occasion of the 80th birthday of Prof. Friedrich Hirzebruch. The lectures address a general audience and aim at illustrating the relation between mathematics and art, society and other fields.

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.

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.

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.

"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 on "Asymptotic Counting and L-Functions"

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.

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.
