## 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.

## 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.

## Seminar on Topological insulators

## Seminar on tilting characters of reductive groups

## Geometric recursion learning seminar

### Content

Geometric Recursion (GR) is a fairly new technique that extends the usual Topological Recursion (TR) theory by means of Teichmüller theory, and relates to several results of Maryam Mirzakhani. It sits in the interplay between many areas of mathematics as mathematical physics, algebraic geometry and category theory.

The first part of the learning seminar aims to define and introduce GR. The second part of the seminar is more open and it will be tailored during the first weeks according to the taste of the participants towards open research questions.

## Seminar Geometry and Dynamics

## Working group on Grothendieck-Teichmüller groups

The idea of this working group is to have an exchange of points of views

concerning a tool which connects both geometric and arithmetic areas.

People who do not necessarily want to give a talk, are also welcome.

## Learning seminar on deformation theory

The goal of the seminar is to rigorously understand the statement ''Every deformation problem in characteristic zero is controlled by a differential graded Lie algebra". This statement has long been a philosophy/guiding principle when studying deformations of algebraic or geometric structures. By the end of the seminar we aim to understand the statement and proof of its following modern incarnation:**Theorem **(Lurie, Pridham)

## IMPRS seminar on K-theory

## Learning seminar on quantum field theory and BV formalism

The aim of this learning seminar is two fold

1) give a gentle introduction to the basics of quantum field theory (path integral, n-point functions and Wick theorem, Feynman diagrams, gauge fixing and BRST cohomology),

2) present some recent progress related to the BV and BF-BFV formalisms.

We will cover the first part in April and the second one in May.

When?

Every Thursday morning from 10:15 till 12:00 with a 15 minutes break at 11:00

Plan of the talks :

## Seminar Aachen-Bonn-Köln-Lille-Siegen on Automorphic Forms

This is the 52nd meeting of the joint French-German seminar on automorphic forms

which is organized by the universities of the five cited cities. Everybody who is interested in

automorphic forms is welcome. We encourage in particular young researchers to participate

and to report on their work in one of our meetings. For further information concerning this

meeting please send an email to moree$@$mpim$-$bonn$.$mpg$.$de
