## 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 Geometry and Dynamics

## Working group on Grothendieck-Teichmüller groups

## Learning seminar on deformation theory

Goal of the seminar is to rigoruosly understand the statement ''Every deformation problem in characteristic zero is controlled by a dgla".

#### Contents:

Part I

(Where we see that deformations and dgLa's have something to do with each other)

I.1 - Motivation and 1 or 2 examples of deforming a structure. Maybe Associative algebras, Lie algebras, or complex structures.

I.2 - The deformation functor coming from that example

I.3 - The dgLa coming from that example, and Maurer Cartan equation.

I.4 - The relation between the two.

## 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

## Workgroup Seminar Nikolaus

## Informal mini-workshop: A celebration of instantons

Outline: We will have an informal session on instanton gauge theory and various applications to SU(2)-representation varieties of 3-manifolds, and to problems in 3-manifold topology and knot theory. Our aim is to also discuss in more detail some of the technical tools involved.

## Seminar on Kac-Moody algebras and ind-pro-topologies
