Seminar on Algebra, Geometry and Physics

In recent work with S. Naito, D. Sagaki, A. Schilling, and M. Shimozono, we show that in all untwisted affine types the specialization of a Macdonald polynomial at t=0 is the graded character of a tensor product of one-column Kirillov-Reshetikhin (KR) modules.

Torsion (of a manifold) as a function on the variety of representations (of its fundamental group)

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: Status and Recent Work

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.

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.

Seminar on Algebra, Geometry and Physics

We consider a class of non-linear PDE systems, whose equations possess Noether identities (the equations are redundant), including non-variational systems (not coming from Lagrangian field theories), where Noether identities and infinitesimal gauge transformations need not be in bijection. We also include theories with higher stage Noether identities, known as higher gauge theories (if they are variational).

According to a theorem of Eliashberg and Thurston a C2-foliation on a closed 3-manifold can be C0-approximated by contact structures unless all leaves of the foliation are spheres. Examples on the 3-torus show that every neighbourhood of  a foliation can contain
infinitely many non-diffeomorphic contact structures. In this talk we show that this is rather exceptional: In many interesting situations the contact structure in a sufficiently small
