I will describe an invariant for a smooth manifold with some additional topological structure. This will be a meromorphic function on the algebraic set of complex representations of its fundamental group defined using either spectral geometry (of a Riemannian metric) or a triangulation or the dynamics of a nice vector field.

The 3x+1 Problem is a long-standing conjecture. Let T be 
a map from the positive integers into itself, where T(x)=x/2 if x is even 
and T(x) = (3x+1)/2 if x is odd. The conjecture asks whether, under 
iteration of the map T, any positive integer eventually reaches the value 
one. This talk gives a survey of the various approaches and results, 
intersecting areas such as number theory, dynamical systems, and 
functional equations. The speaker's approach involving generating
functions is also presented.

“Wechselwirkung” - Brigitte Heintze stellt Zeichnungen auf mathematischen Notizblättern aus

Posted in

Das Max-Planck-Institut für Mathematik lädt zur Eröffnung der Ausstellung am 27.3.2013 um 18:00 Uhr im Atrium des Instituts ein. MPIM-Direktor Werner Ballmann spricht ein Grußwort, der Kunsthistoriker Dr. Peter Lodermeyer führt in die Ausstellung ein. Die Künstlerin wird anwesend sein. Die Veranstaltung wird vom Hausdorff Center for Mathematics unterstützt. 

Ausstellungsdauer: 28.3.-6.5.2013
Öffnungszeiten: Montag bis Freitag von 10:00 - 16:00 Uhr (ausser an Feiertagen)

Brigitte Heintze studierte Malerei und klassische Gobelinweberei an der Fachhochschule für Kunst und Design Köln bei den Professoren Helmut Kaldenhoff und Hubert Schaffmeister. Seit 1986 arbeitet sie als freischaffende Künstlerin. Sie lebt und arbeitet heute in Stadtbergen bei Augsburg. Neben zahlreichen Ausstellungen in Deutschland präsentierte sie ihre Arbeiten auch mehrfach im Ausland. Sie erhielt ein Druckgrafikstipendium in Weimar, verbunden mit einer Einzelausstellung sowie Preise des Landratsamtes Landsberg und der Kreissparkasse Augsburg.

Brigitte Heintze beschäftigt sich hauptsächlich mit Zeichnung und Druckgrafik. In den hier ausgestellten Arbeiten hat sie Forschungsblätter ihres Mannes benutzt, die eigentlich für den Papierkorb gedacht waren, und hat sie als Untergrund und Inspiration für ihre Zeichnungen und Mischtechniken verwendet. Feine Linien, Strukturen und Geflechte wechseln sich ab mit geometrischen Figuren und antworten auf die mathematischen Formeln – oder lassen sie gänzlich außer Acht.

60 Blätter enthält diese Werkgruppe, die innerhalb relativ kurzer Zeit im Jahr 2010 entstand und die jetzt im Max-Planck-Institut für Mathematik präsentiert wird. Die äußerst spartanische Rahmung in Plakattaschen aus farblosem Acryl unterstreicht das Notizenhafte der Arbeiten. Dennoch zeichnen sich die Blätter durch höchstes zeichnerisches Können aus, der dem, der sich darauf einlässt, größtes Vergnügen
bereitet.

Program and Abstracts of Student seminar on higher categories

Course Description:

We want to understand the comparison problem in higher category theory, i.e. for structures which have objects, 1-morphisms, 2-morphisms, etc. Higher categories have arisen in many areas of mathematics, as well as in formalisms for quantum field theory. There are many alternative models for higher categories and the goal of this course is to understand some of them and their inter-relationships.

In the study of Hilbert, Jacobi and orthogonal modular forms
of low weight over number fields it is essential to understand the
representations of Hilbert modular groups or of certain two-fold
central extensions. In the case of the field of natural numbers it is
known that the key to the study of all representations of the modular
group $SL(2,Z)$ which are interesting in the mentioned context are
the Weil representations associated to finite quadratic modules. In
analogy to the case of the field of rational numbers we developed a

 We study principal bundles for strict Lie $n$-groups over simplicial manifolds. Given a Lie group $G$, one can construct a principal $G$-bundle on a manifold $M$ by taking a cover $U$ of $M$, specifying a transition cocycle, and then quotienting $U\times G$ by the equivalence relation generated by the cocycle. We demonstrate the existence of an analogous construction for arbitrary strict Lie $n$-groups. As an application, we show how our construction leads to a simple finite dimensional model of the Lie 2-group String($n$).

The Witten genus and topological modular forms

I will give a fairly high level introduction to topological modular forms (Tmf) and their relationship to the Witten genus. Tmf was constructed, in part, as the target of a cohomological lift of Witten genus. The Witten genus assigns a modular form to a string manifold and this assignment is invariant under string bordism. This is analogous to the A-hat genus which assigns to a spin manifold an elliptic operator which, in turn, defines a formal difference of vector spaces. Moreover the A-hat genus is invariant under spin bordism.
