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.

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.

This often leads to further mathematical interaction, and in any case it is very interesting to know what one's colleagues are working on.

This implies two things:

  1. When you speak at the Oberseminar you should try to make sure that your talk is understandable and interesting to everyone, not just to the people in the same field. (We have many specialized seminars where you can present your work at a more technical level.)
  2. Please always attend the Oberseminar, even if the title of the talk seems technical, because you know that the speaker is going to do a good job. The only reason for absence is that the talk is in your field and thus will be too easy for you.

We hope to see you at the Oberseminar!

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.

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

Christian Blohmann, Sylvain Lavau, Joao Nuno Mestre, Joost Nuiten

Location: 
MPIM Seminar Room

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)
There is an equivalence of $\infty$-categories between the $\infty$-category of formal moduli problems and the $\infty$-category of dgLa's over a field of characteristic zero.

Everyone is welcome, whether to give a talk or simply attend. If you think you'd like to give a talk please come to the first meeting or get in touch with one of the organizers.


Contents

In the first part we will see some deformation problems that naturally give rise to dgLa's, and that can also be encoded in deformation functors (also called formal moduli problems). We will see that the two are related by the Maurer-Cartan equation.

In the second part we will study how to construct a deformation functor out of a dgLa using the Maurer-Cartan equation. Conversely, we will build a dgLa out of a deformation functor. For that, we will need to understand some categorical properties of the $\infty$-category of dgLa's - roughly, that we can describe it in terms of generators and relations. This will be done making use of the Chevalley-Eilenberg complex of a dgLa, so that we can work in differential graded local Artinian rings (dgArt) instead.

In the third part we will see that the construction of a dgLa out of a deformation functor is an equivalence of $\infty$-categories between formal moduli problems and dgLa's. Finally, we will see that the inverse of this equivalence is given by the Maurer-Cartan construction.


Talks

  1. Motivation and examples
  2. Deformation Problems and Moduli Problems  (Notes by Alex)
  3. Deformation functors - Modern approach and the MC equation (Notes by Joao)
  4. The Chevalley-Eilenberg complex $C^*$, and how it is related to the Maurer-Cartan equation (Notes by Joost)
  5. The model category dgLa
  6. Koszul duality I - $C^*$ and its adjoint
  7. Koszul duality II - $C^*$ is an equivalence (sometimes) (Notes by Sylvain)
  8. Proof of the equivalence in the Main Theorem, part 1(Notes by Christian)
  9. Proof of the equivalence in the Main Theorem, part 2
  10. The inverse of the equivalence is given by Maurer-Cartan

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
