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.

Universal family for subgroups of an algebraic group

I describe the construction of a moduli space for the connected subgroups of an algebraic group, and of a universal family. I give a quick illustration of the notion of universal families, trough Grassmann varieties, then discuss in turn the construction of a moduli space and of a universal family, balancing general statements and examples.

The stabilization hypothesis of Breen,Baez and Dolan states that k-fold monoidal n-category is "the same" as (k+1)-fold (and therefore $\infty$-fold) monoidal n-category if k is grater or equal to n+2. In the first half of my talk I will explain this hypothesis in an informal manner and I will relate it to the geometry of configuration spaces of k points in $R^n$. In somewhat more technical second half I will introduce n-braided operads and will give a sketch of a proof of a stabilization theorem for n-braided operads.

Irreducibility of the moduli space $I_n$ of mathematical instanton vector bundles on the projective space $P_3$ for arbitrary odd second Chern class $n$

The problem of description of the moduli space $I_n$ of mathematical instanton vector bundles on the projective space $P_3$ has been a challenging problem since 70's. It was conjectured by R.Hartshorne in 1976 that $I_n$ is irreducible for an arbitrary second Chern class $n>0$. This problem has an affirmative solution for small values of $n$, up to $n=5$. Namely, the cases $n=1,2,3,4$ and 5 were settled by Barth (1977), Hartshorne (1978), Ellingsrud-Stromme (1981), Barth (1981) and Coanda-Tikhomirov-Trautmann (2003), respectively.

Suppose that the circle acts on a symplectic manifold in a Hamiltonian fashion. Under certain "minimal'' conditions of the fixed point set of the action, we classify the integral cohomology ring and the Chern classes of the manifold, and we classify the circle action.

A numerical test of the generalized Birch and Swinnerton-Dyer conjecture

Date:

Location: 
MPIM Lecture Hall

In its crudest form the generalized Birch and Swinnerton-Dyer relates the order of vanishing of an L-function at the center of the critical strip to the rank of a Chow group. This talk describes the conjecture and an attempt to put it to a modest test in the case of motives of the form Sym$^3H^1(E)$, where E is an elliptic curve over Q. This is joint work with Joe Buhler and Jaap Top.

Representations up to homotopy of Lie algebras have attracted recently much attention. On the other hand J. Baez has introduced a way to build a homotopy Lie algebra out of a Lie algebra and an n-cocycle. We show in this work a common framework enabling to generalize both notions (replacing Lie algebras by homotopy Lie algebras) and extend them for other types of algebras (commutative and associative). The main tool is the language of homological vector fields on products of formal manifolds. This is a joint work with John Baez.

Harder's conjecture and ratios of standard L-values

I will explain how the Bloch-Kato conjecture leads to the following conclusion: any large prime dividing a critical value of the L-function of a classical Hecke eigenform of level 1, should also divide a certain ratio of critical values for the standard L-function of a related genus 2 (and in general vector-valued) Hecke eigenform F. This can be proved in the scalar-valued case, and there is experimental evidence in the vector-valued case (where the relation between f and F is a congruence of Hecke eigenvalues conjectured by Harder).
