Friedrich Hirzebruch Lecture

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!

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.

Part II
(Where we see how to travel between deformation problems and dgLa's)

II.1 - Deformation Functors (another name for formal deformation problems)
II.2 - DgLa's and Chevalley complexes
II.3 - Process A - Maurer-Cartan, or how to get a deformation functor out of a dgLa.
II.4 - Process B - How to get a dgLa out of a deformation functor:
      - Step 1 - from free dgLa's to dgArt
      - Step 2 - compose Step 1 with the deformation functor F to get a functor from free dgLa's to Simplicial sets. Out of these build a dgLa by some sort of  limit, or describing via a resolution by free things.

Part III
(Where we see that A and B are inverse processes up to homotopy)

III.1 - Process B is an equivalence for some formal reasons
III.2 - Intermezzo - technical tools from infinity-categories and homotopy theory
III.3 - The inverse up to homotopy of the process B is process A

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
