Conference on "Enumerative Arithmetic and the Cohen–Lenstra Heuristics", June 3 - 7, 2019
 

The purpose of the workshop is to survey recent progress and promising future research directions on statistical properties of class groups of number fields, of Selmer groups of elliptic curves, and related topics. The conference will feature a mixture of overview talks and more specialised research talks, as well as contributed talks by early career researchers. There will also be ample time for informal discussions and collaborations.

SageMath (http://www.sagemath.org/) is an open source software for mathematical computations. It gathers hundreds of specialized libraries and softwares in a unified Python interface.

On the afternoon of July 24th, there will be a presentation of SageMath at MPI Bonn (1:00 - 4:00). After tea time (ie from 5pm) several SageMath experts will be there on the fourth floor in case you need help for installing SageMath on your computer or need advice on how to carry a specific computation.

This event is part of a week long workshop taking place at the Computer Science department of Bonn University.

Conference on "Integrability, Geometry and Moduli" July 29 - August 2, 2019
 

This is a conference in honor of Motohico Mulase's 65th birthday. It will cover recent advances around the following themes

  • Quantization of moduli spaces, in particular the Hitchin moduli space of Higgs bundles
  • Gromov-Witten theory, Frobenius manifolds, integrable hierarchies, cohomological field theories
  • Geometry of quiver varieties, wall-crossing phenomena
  • Mirror symmetry, topological string theory, quantum invariants of 3-manifolds
  • Topological recursion, quantum curves, and application to geometry and enumerative problems (Hurwitz theory, random matrix theory, ribbon graphs)

Connections between these fields are apparent from the physics perspective and research is trying to make rigorous sense of these relationships. Encouraging the exchanges between mathematicians and theoretical physicists will thus be an important dimension of the conference. More details available soon.

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.

W. Lowen and M. Van den Bergh defined a deformation theory for Abelian categories, such that deformations of the category of (quasi)coherent sheaves on an affine variety Spec A coincide with deformations of the algebra A, which are controlled by the Hochschild cochain complex equipped with the Gerstenhaber bracket.

Non-abelian Kummer maps for curves

Parent event: 
Number theory lunch seminar

The Q_l-pro-unipotent non-abelian Kummer map associated to a curve X is a certain function controlling the existence of Galois-invariant paths between points of X, and plays an important role in the non-abelian Chabauty method for finding rational points. In this talk, I will report on a project with Netan Dogra, in which we compute these maps explicitly when the base field is p-adic, obtaining a description of them in terms of harmonic analysis on the reduction graph of X. As a result, we are able to prove injectivity results for these maps.
