## 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.

Extra talk

In this first out of three talks, we will explain in detail the transverse spheres lemma by Quinn, which is the key geometric result that allows for the separation of infinitely many locally finite immersed 2-discs in a non-compact 4-manifold. The phenomena coming out of this lemma also allow one to understand why Quinn’s proof of this separation of infinite data is as complex as it is. We will explain these phenomena for future reference.

MPIM Topology Seminar

Bökstedt periodicity refers to Bökstedt's seminal description of topological Hochschild homology of finite fields. I will discuss a recent project with T. Nikolaus on computations of THH based on a relative version of Bökstedt periodicity. Our main applications are quotients of discrete valuation rings, generalizing Brun’s results for Z/p^n.

MPIM Lecture Hall

We study the homology of Riemannian manifolds of finite volume that are covered by a product of r copies  of the hyperbolic plane. Using a variation of a method developed by Avramidi and Nyguen-Phan, we show that any such manifold  M possesses, up to finite coverings, an arbitrarily large number of compact oriented flat totally geodesic r-dimensional submanifolds whose fundamental classes are linearly independent in the r-th homology group of M.

We formulate the notion of pre-Calabi-Yau structure via the higher cyclic Hochschild complex and study its cohomology.
A small quasi-isomorphic subcomplex in higher cyclic Hochschild complex gives rise to the graphical calculus of $\xi\partial$-monomials.

Number theory lunch seminar

We consider upper bounds of the Riemann zeta function on the 1-line and demonstrate a link with the maximum of the function S(t) - the remainder in the formula for the number of non-trivial zeros of height t in the critical strip. In particular, we show that a conjecture of Littlewood on the maximum of \zeta(1+it) follows from a folklore conjecture on the max of S(t).

## 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.

Datum:
Don, 2013-01-31 15:00 - Don, 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.

## Reading group on "Integer points in polyhedra"

Posted in
Organiser(s):
Gaetan Borot, Alessandro Giacchetto
Location:
MPIM Seminar Room

We will introduce the algebra of (indicator functions) of polyhedra and study its properties. Linear forms on this algebra produce functions on the set of polytopes (i.e. bounded polyhedra), that are compatible with set-theoretic decompositions of polyhedra. For polytopes, the lattice point count or the volume are examples of such linear forms.
