Recent developments in Quantum Topology -- Cancelled --

Posted in

Talk

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

Parent event:

Seminar on Algebra, Geometry and Physics/joint with HU Berlin

https://hu-berlin.zoom.us/j/61339297016

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

Affiliation:

École Polytechnique Fédérale de Lausanne (EPFL)

Date:

Thu, 2021-04-29 16:30 - 18:00

Parent event:

Oberseminar Differentialgeometrie

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.

Program and Abstracts of MPI-Oberseminar

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.
