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.

Area minimizing surfaces for singular configurations of boundary curves

Posted in
Speaker: 
Paul Creutz
Affiliation: 
Universität Köln
Date: 
Thu, 2020-11-05 16:30 - 18:00
Parent event: 
Oberseminar Differentialgeometrie

Let g be a nonnegative integer and C be a finite configuration of disjoint Jordan curves in Euclidean space. Then, by a classical result of Douglas, there is an area minimizer among all surfaces of genus at most g which span C. In the talk we will discuss a generalization of this theorem to singular configurations C of possibly non-disjoint or self-intersecting curves. Furthermore, the talk will contain new existence results for regular curve configurations C in general metric ambient spaces.
