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.

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.

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.

André-Quillen cohomology theory of an algebra over an operad

Joan Millès
Date:

Location: 
MPIM Lecture Hall
Parent event: 
MPI-Oberseminar

Following the ideas of Quillen and by means of model category structures, Hinich, Goerss and Hopkins have developped a cohomology theory for (simplicial) algebras over a (simplicial) operad. Thank to Koszul duality theory of operads, we describe the cotangent complex to make these theories explicit in the differential graded setting. We recover the known theories as Hochschild cohomology theory for associative algebras and Chevalley-Eilenberg cohomology theory for Lie algebras and we define the new case of homotopy algebras.

Monodromy invariants of the fibrations over projective line

One of the main problems of geometry is to find discrete invariants distinguishing geometric objects up to some equivalence. In algebraic geometry, the classical approach, based on ideas of Riemann, Hurwitz, Lefschetz, consists of representations of complex algebraic manifolds either as finite coverings of the projective spaces (generic coverings) or as codimension one fibrations over the projective line (Lefschetz pencils).

We discuss rank one and higher rank superrigidity for the isometry groups of a class of complexes which includes hyperbolic buildings as a special case. Our method uses harmonic maps to singular spaces.

MPI-Oberseminar

Whittaker functions are special functions on reductive groups, which are naturally arising in the theory of automorphic representations. The talk is devoted to recent results (joint with A. Gerasimov and D. Lebedev) on explicit construction of $q$-deformation of Whittaker functions for the group $GL(N,\mathbb{R})$. In the first part of my talk I will introduce two (integral) representations of $GL(N)$-Whittaker function, using two different limits of Macdonald polynomials. The first representation is a $q$-deformation of the classical Gelfand-Zetlin formula for the character.

 The geometric version of weak Mordell-Weil problem for cubic surfaces over number fields,- finite generation of the set of rational points,- still remains unsolved problem. At the HIM workshop "Diophantine Equations", Spring 2009, I formulated the program of a new approach to this problem, with model theoretic flavor.
