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.

MPIM Topology Seminar
An aspherical manifold is a manifold whose universal cover is contractible, i.e. a K(\pi,1)-manifold. Borel conjectured that any two closed aspherical manifolds with isomorphic fundamental groups are homeomorphic, in fact, that the structure set of an aspherical manifold is trivial. Wall asked if a K(\pi,1)-space which satisfies Poincare duality is homotopy equivalent to a closed manifold.

Bilinear discretization of quadratic vector fields: integrability and geometry

We discuss dynamics of birational maps which appear as bilinear discretizations of quadratic vector fields. The corresponding dynamical systems turn out to be integrable much more often than could be expected. Various aspects of integrability of birational dynamical systems will be discussed, along with remarkable geometric structures behind some of the particular examples.

Geometry without spaces: a hyperbolic parable

Speaker: 
Nicolas Monod

École Polytechnique Fédérale de Lausanne (EPFL)
Date: 
Thu, 2021-04-29 16:30 - 18:00

We revisit old ideas that are shared by functional analysts and logicians alike, in order to do hyperbolic geometry without bothering with practicalities such as spaces or dimension.

Our main interest will be the interplay between (real or complex) hyperbolic geometry and group representations.

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): 
C. Kaiser
Date: 
Thu, 2013-01-31 15:00 - Thu, 2026-12-31 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.
