Organiser(s): 
Christian Blohmann, Marius Crainic, Ioan Marcut, Ieke Moerdijk, Steffen Sagave
Date: 
Thu, 2018-03-08 13:45 - Fri, 2018-03-09 17:00
Location: 
MPIM Lecture Hall

This is the eleventh of a series of  short workshops jointly organized by the Geometry/Topology groups in Bonn, Nijmegen, and Utrecht, all situated along the Lower Rhine. The focus lies on the development and application of new structures in geometry and topology such as Lie groupoids, differentiable stacks, Lie algebroids, generalized complex geometry, topological quantum fi eld theories, higher categories, homotopy algebraic structures, higher operads, derived categories, and related topics.

Rational homology cobordisms of plumbed manifolds and arborescent link concordance

Posted in
Speaker: 
Paolo Aceto
Affiliation: 
Alfréd Rényi Institute of Mathematics, Budapest/MPIM
Date: 
Mon, 2018-02-26 16:30 - 18:00
Location: 
MPIM Lecture Hall
Parent event: 
MPIM Topology Seminar

We investigate rational homology cobordisms of 3-manifolds with non-zero first Betti number.
This is motivated by the natural generalization of the slice-ribbon conjecture to multicomponent links.

We introduce a systematic way of constructing rational homology cobordisms between plumbed 3-manifolds and concordances between arborescent links.

We then describe a sliceness obstruction based on Donaldson's diagonalization theorem that leads to a proof of the slice-ribbon conjecture for 2-component Montesinos' links up to mutation.

Quadratic Relations in Feynman Categories

Speaker: 
Ralph Kaufmann
Affiliation: 
Purdue University, West Lafayette
Date:

Location: 
MPIM Lecture Hall

I will start with a brief introduction to Feynman categories, and then explore the consequences of
quadratic relations for the morphisms in Feynman categories.

In the first part of the talk, I show how this leads to cubical complexes and prove that in this
way both the complex for moduli spaces of curves and the cubical complexes for Cutkosky rules
and calculations for Outer space arise naturally from push-forwards.
In the second part, I study generalizations of the quadradtic relations, which naturally lead

I will consider the integers $\alpha$ of the quadratic field $ \mathbb{Q} (\sqrt[]{d})$ with $d$ is a square-free integer.  Using the embedding into $ \text{GL}(2,\mathbb{R})$ we obtain bounds for the smallest positive integer  $\nu$ such that $\alpha^\nu\equiv 1\bmod p.$ More generally, if $\mathcal{O}_{f}$ is a number ring of conductor $f$, we study the first integer $n=n(f)$ such that $\alpha^n\in\mathcal{O}_{f}$. We obtain bounds for $n(f)$ and for $n(fp^{k})$.

The Hilbert scheme of points of affine 3-space

Andrea Ricolfi
Affiliation: 
University of Stavanger/MPIM
Date: 
Fri, 2018-03-02 14:15 - 16:30
Location: 
MPIM Lecture Hall

We describe the scheme structure of the Hilbert scheme of points of affine 3-space,
in terms of representations of the Jacobi algebra of a quiver with potential. This exhibits the Hilbert scheme of points as the critical locus of a regular function on a smooth variety.
We discuss the torus action on the Hilbert scheme and its Euler characteristic.
 

Hecke's integral formula and Kronecker's limit formula for an arbitrary extension of number fields

Date:

Location: 
MPIM Lecture Hall

The classical Hecke's integral formula expresses the partial zeta function of real quadratic fields as an integral of the real analytic Eisenstein series along a certain closed geodesic on the modular curve. In this talk, we present a generalization of this formula in the case of an arbitrary extension E/F of number fields. As an application, we present the residue formula and Kronecker's limit formula for an extension E/F of number fields, which gives an integral expression of the residue and the constant term at s=1 of the``relative'' partial zeta function associated to E/F.

On the periodicity of geodesic continued fractions

Parent event: 
Number theory lunch seminar

In this talk, we present some generalizations of Lagrange's periodicity theorem in the classical theory of continued fractions. The main idea is to use a geometric interpretation of the classical theory in terms of closed geodesics on the modular curve. As a result, for an extension F/F' of number fields with rank one relative unit group, we construct a geodesic multi-dimensional continued fraction algorithm to``expand'' a basis of F over the rationals, and prove its periodicity. Furthermore, we show that the periods describe the relative unit group.

Friedrich Hirzebruch Lecture

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.

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.

What is the category of representations of classical Lie algebras of "infinite rank"?

The classical Lie algebras sl, so, sp "of infinite rank" in the naive sense have   uncountably many nonconjugate Borel subalgebras. Therefore the definition of categories of their representations involves choices. A natural choice is a Dynkin Borel subalgebra. In this talk, I will advocate for another choice, namely that of a perfect Borel subalgebra. In addition, I will impose the condition of  large local annihilator on the objects of the category. The resulting category is a nice highest-weight category  with standard objects, but without costandard objects.
