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.

Applications of virtual fundamental classes to enumerative geometry

Posted in
Speaker: 
Rosa Schwarz
Affiliation: 
Leiden University
Date: 
Mon, 2021-01-25 10:30 - 12:00

The aim of this talk is to show why understanding the construction of a virtual fundamental class is useful: firstly we do this via computing these in some examples of moduli spaces of stable maps and secondly by linking these classes to Gromov-Witten invariants and thus to certain problems in enumerative geometry. I will start with a recap from the summer (17th August), when moduli spaces of stable maps were introduced, giving explicit examples along the way.

Cut and paste invariants of manifolds via algebraic K-theory

Parent event: 
MPIM Topology Seminar

Recent work of Campbell and Zakharevich has focused on building machinery for studying scissors congruence problems via algebraic K-theory. Their main application was the study of the Grothendieck ring of varieties. In this talk, I will present an application of their framework to the study of cut and paste invariants of manifolds. In particular, I will talk about the construction of a spectrum that recovers the classical "cut and paste" groups for manifolds on \pi_0.

Tame geometry and Hodge theory

Posted in
Speaker: 
Bruno Klingler
Affiliation: 
HU Berlin
Date: 
Tue, 2021-01-26 14:00 - 15:30

Originating in Grothendieck's "Esquisse d'un programme", tame geometry has been developed by model theorists under the name "o-minimal structures". It studies structures where every definable set has a finite geometric complexity. It has for prototype real semi-algebraic geometry, but is much richer.

Generic regularity of min-max minimal hypersurfaces

Posted in
Speaker: 
Yevgeny Liokumovich
Affiliation: 
University of Toronto
Date: 
Thu, 2021-01-28 16:30 - 18:00

Minimal hypersurfaces in 8-dimensional Riemannian manifolds may have isolated singularities. However, it follows from the results of R. Hardt, L. Simon and N. Smale that one can perturb away singularities of an area minimizing minimal hypersurface by a small change of the metric. I will talk about a similar problem for min-max minimal hypersurfaces (joint work with Otis Chodosh and Luca Spolaor). We show that for a generic 8-dimensional Riemannian manifold with positive Ricci curvature, there exists a smooth minimal hypersurface.

Detailed list of recurring seminars, series of talks, and courses or lectures comprising multiple talks. For an overview see also the calendar.

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

Posted in
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.

The Uryson width of an n-manifold gives a way to describe how closely it resembles an (n−1)-dimensional complex. It turns out that this is a useful tool to approach several geometric problems.
