Workshop on "Combinatorics, Resurgence and Algebraic Geometry in Quantum Field Theory", August 19 - 23, 2024

Workshop on "Combinatorics, Resurgence and Algebraic Geometry in Quantum Field Theory", August 19 - 23, 2024

The study of perturbative quantum field theory has shown a surprising need for the latest advances in algebraic geometry and combinatorics. The field also incorporates the very actively developed theory of resurgence, which has promising potential for applications to both topology and quantum field theory.

This workshop aims to advance this field by bringing together top experts. The goal is to foster discussions on recent results, encourage collaboration, generate new ideas, explore the connections in perturbative quantum field theory, and offer a platform for junior researchers.

This workshop consists of a fixed list of participants. It is not possible to register.

Workshop on "Dualisable Categories & Continuous K-theory"

Workshop on "Dualisable Categories & Continuous K-theory", September 9 - 13, 2024

Algebraic K-theory is an object that sits at the centre of large parts of algebra, geometry, and topology because of its universal role as a receptacle to count other mathematical objects with signs. However, since its invention, a phenomenon often called the Eilenberg swindle - which says that the algebraic K-theory of a category which is too large must necessarily be zero - has been accepted as a fundamental limit to the theory.

Distinguishing Brill--Noether loci

Date:

Location: 
MPIM Lecture Hall

Classical BrillNoether theory studies linear systems on a general curve in the moduli space $\mathcal{M}_g$ of algebraic curves of genus $g$. A refined BrillNoether theory studies the linear systems on curves with a given BrillNoether special linear system.

Parent event: 
Physical Math Seminar
In this talk we will give a relaxed introduction to TMF. First, we will start with some discussion of elliptic cohomology and the moduli space of elliptic curves. This will lead us to the definition of TMF.

For certain groups G, acting on a manifold X, an equivariant localisation theorem relates H_*(X x_G EG) to the homology of the fixed point set of the G-action (for intuition, we use the homotopy quotient X x_G EG as an analogue of the quotient X/G when G does not act freely). This is a great tool to calculate the homology of X x_G EG, but in many cases (such as in symplectic geometry) one would like to apply localisation more generally to fibrations over some homotopy quotient. We will demonstrate that one can reinterpret the classical equivariant localisation theorem (e.g.

(jt with D. Gaistgory, A. Genestier and V. Lafforgue) Let F be a local field of equal characteristic and G be a reductive group over F. The conjectural categorical form of the local Langlands correspondence proposed by Fargues and Scholze is an equivalence of categories between on one side the category of $\ell$-adic sheaves on $\Bun_G(X_{FF})$ the stack of $G$-torsors on the Fargues-Fontaine curve and and on the other side the category of coherent sheaves on the stack of $L$-parameters.

The universal property of bordism rings of manifolds with commuting involutions

Universität Bonn

Parent event: 
MPIM Topology Seminar

My talk concerns bordism rings of compact smooth manifolds equipped with a smooth action by a finite group. I will start by recalling classical results on the subject from the 60's and 70's, mostly due to Conner-Floyd, Boardman, Stong and Alexander. Afterwards I will discuss joint work with Stefan Schwede in which we prove an algebraic universal property for the collection of all bordism rings of manifolds with commuting involutions.

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.

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.
