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

Organiser(s):
Hongyi Chu & Bruno Stonek
Date:
Mon, 2020-08-17 09:00 - Fri, 2020-08-21 17:00
Location:
MPIM Lecture Hall

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.

Number theory lunch seminar

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 $p$.
