Recent developments in Quantum Topology -- Cancelled --

Posted in

We will review the basics of quantum topology such as the colored Jones polynomial of a knot, its standard conjectures relating to asymptotics, arithmeticity and modularity, as well as the recent quantum hyperbolic invariants of Kashaev et al, their state-integrals and their structural properties. The course is aimed to be accessible by graduate students and young researchers.

There are many formulas that express interesting properties of a finite group G in terms of sums over its characters. For evaluating or estimating these sums, one of the most salient quantities to understand is the character ratio:

Algebraic geometry of the Lagrangian correspondence of Gaiotto

From a consideration of N=2 SUYM in four dimensions, Gaiotto [1] has conjectured that a certain scaling limit of twister lines in the space of G-Higgs bundles converge to an oper. For holomorphic G-Higgs bundles, the conjecture has been settled for an arbitrary simply connected algebraic group G in 2016 in a joint paper with my collaborators [2].

On a mean value result for a product of L-functions

Speaker: 
Nicole Raulf

Université de Lille
Date: 
Wed, 2019-08-21 14:30 - 15:30
Location: 
MPIM Lecture Hall
Parent event: 
Number theory lunch seminar

The asymptotic behaviour of moments of L-functions is of special interest to number theorists and there
are conjectures that predict the shape of the moments for families of L-functions of a given symmetry type.
However, only some results for the first few moments are known. In this talk we will consider the asymptotic
behaviour of the first moment of the product of a Hecke L-function and a symmetric square L-function
in the weight aspect. This is joint work with  O. Balkanova, G. Bhowmik, D. Frolenkov. 

Persistent homology (from a mathematical point of view)

Speaker: 
Grégory Ginot
Affiliation: 
Université Paris 13, Institut Galilée/MPIM
Date: 
Thu, 2019-08-22 15:00 - 16:00
Location: 
MPIM Lecture Hall
Parent event: 
MPI-Oberseminar

The goal of the talk is to present the basics of persistent homology which is one of the primary tools in  applied algebraic topology and topological data analysis.
We hope to explain the mathematical ideas behind it, some of its current challenges and relations to sheaf theory.

Rationality of Fano 3-folds over nonclosed fields

Affiliation: 
Steklov Mathematical Institute, Moscow/MPIM
Date:

Location: 
MPIM Lecture Hall

The rationality problem for smooth Fano threefolds over algebraically closed fields is basically solved.
In this talk I will discuss rationality  of forms of these  Fanos over nonclosed fields of characteristic 0.
I will concentrate on the case where the  Picard number  equals 1.

The talk is based on joint work with Alexander Kuznetsov (in progress).

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.

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.

Pentagramma Mirificum (the miraculous pentagram) is a beautiful geometric construction studied by Napier and Gauss. Its algebraic description yields the simplest instance of cluster transformations, a remarkable family of recurrences which arise in diverse mathematical contexts, from representation theory and enumerative combinatorics to theoretical physics and classical geometry (Euclidean, spherical, or hyperbolic).

The theory of random Delaunay triangulations of the plane has been proposed by
David-Eynard and others as a discrete model for 2-dimensional quantum gravity: In this model
the role of a continuous metric is played by a Delaunay triangulation while flat metrics
correspond to isoradial triangulations (on which one can define a theory of discrete analyticity).
Like the continuous case, the partition function for this discrete theory is given by a suitably
normalized determinant of a Beltrami-Laplace operator which varies with the choice of
