## MPI-Oberseminar

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

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.

## Workshop on "$\infty$-categories and their applications", August 17 - 21, 2020

The quest for solid foundations for $\infty$-categories started several decades ago, but from the mid-2000s there have been spectacular developments which excitingly accelerated the pace of progress. This workshop will focus on these objects, both in their foundations and in the applications to different fields of mathematics. There will be minicourses on $\infty$-categories and on related topics which have benefited substantially from the $\infty$-categorical viewpoint.

## Geometric Representation Theory

## Twinned conference "Geometric Representation Theory", June 22 - 26, 2020

### Update!

### In light of the current Covid-19 pandemic, we have decided that the conference "Geometric Representation Theory", which was to be held jointly at the Max Planck Institute and the Perimeter Institute, will not be going forward as an in-person event. We are however keen for the event to go ahead remotely, and we are currently investigating how this might be implemented.

## -- CANCELLED -- Stability of polynomials modulo primes

For a polynomial $f\in\mathbb{K}[X]$ over some field $\mathbb{K}$ we define the sequence of polynomials

$$

f^0(X)=X, \quad \text{and} \quad f^{(n)}(X)=f(f^{(n-1)}(X)), \quad n=1,2,\dots

$$

The polynomial $f$ is said to be *stable* if all iterates $f^{(n)}$ are irreducible.

It is conjectured, that for a quadratic polynomial $f\in\mathbb{Z}[X]$, its reduction $f_p\in\mathbb{F}_p[X]$ modulo $p$ can be stable just for finitely many primes $p$.
