Friedrich Hirzebruch Lecture

Posted in
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

Organiser(s):

Thu, 31/01/2013 - 15:00 - Thu, 31/12/2026 - 16:00
Location: 
MPIM Lecture Hall

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!

Miniseries "An introduction to homotopy type theory and univalent foundations"

Organiser(s): 
Barthel, Ozornova, Ray, Teichner
Date: 
Mon, 14/03/2022 - 15:00 - 16:00

For zoom details contact: Barthel, Ozornova, Ray, Teichner.

Miniseries abstract: 
The field of homotopy type theory/univalent foundations (HoTT/UF) presents a new connection between topology and logic. It provides a foundational framework for mathematics where equivalent objects are identified. Moreover, in HoTT the basic objects carry homotopical information making it possible to do homotopy theory in a synthetic way. Using appropriate software, the proofs in HoTT/UF can be verified on a computer.
 
In this mini series, we'll give an introduction to the fundamental ideas of HoTT. The first talk by Jonathan Weinberger gives an introduction to the language of HoTT with a few hints on how this allows for doing synthetic homotopy theory. In the second talk, Léonard Guetta discusses the higher groupoidal structures of path/identity types and relations to Grothendieck's Homotopy Hypothesis. The final talk is given by Paige Randall North (University of Pennsylvania) and provides a detailed discussion of the Univalence Principle, going back to Vladimir Voevodsky, which states that equivalent mathematical structures are indistinguishable.

Miniseries "Local methods in categorical symplectic geometry"

Posted in
Organiser(s): 
Barthel, Ozornova, Ray, Teichner
Date: 
Mon, 24/01/2022 - 15:00 - 16:00

Miniseries abstract: The Fukaya category is an invariant of a symplectic manifold governing the intersection theory of its Lagrangian submanifolds, built from the pseudoholomorphic disks which bound these Lagrangians. One particularly important version for non-compact symplectic manifolds is the partially wrapped Fukaya category, which plays a prominent role in homological mirror symmetry. This miniseries will lead up to a toolbox for computing and studying structural properties of partially wrapped Fukaya categories. One of the key tools is a descent formula, i.e. a cosheaf property with respect to Weinstein sectorial coverings. We will emphasize concrete examples, and homological mirror symmetry will be a recurring point of reference.

Mini series "Motivic tensor-triangular geometry"

Tensor-triangular geometry is a geometric approach to certain classification problems in a wide variety of contexts, ranging from topology to representation theory and algebraic geometry. In a series of three talks we will introduce the audience to this approach, particularly geared towards the study of cohomological (or, "motivic") aspects of algebraic varieties. In the last few years, this has unearthed interesting structures in categories of motives which we will report.
