This
series of lectures is dedicated to recent results concerning the
existence of holomorphic curves on the surfaces of class VII. The first
lecture will be an introduction to the Donaldson theory. We will present
the fundamental notions and some important results in the theory,
explaining ideas of the proofs. In the second lecture we will present
the theory of holomorphic fiber bundles on complex surfaces, the
stability notion, moduli spaces and the Kobayashi-Hitschin
correspondence that links moduli spaces of stable fiber bundles (defined
in the fram of complex geometry) to moduli spaces of instantons
(defined in the frame of the Donaldson theory). In the last two lectures
we will prove the existence of holomorphic curves on minimal surfaces
of class VII with b2=1 or 2 and we will present the general strategy and
the last results obtained in the general case. Mot(s) clés libre(s) : mathématiques, Grenoble, école d'été, institut fourier, summer school, feuilletages, COURBES PSEUDOHOLOMORPHES

Les DEA, DESS et Masters de santé publique ont été identifiés à partir du catalogue mis en ligne sur le site de l'ONISEP. A deux reprises, en août 2003 et en août 2004, les sites des formations extraites du catalogue ont été recherchés (Google). Tous les sites ont été systématiquement visités à l'aide d'une grille de recueil standardisée (type de formation, public visé, pré-requis, programme, nom du responsable, adresse courriel, forum, FAQ). Les diplômes français sont comparés aux Masters of Public Health (MPH) offerts par les universités américaines et répertoriés sur le site CEPH.

Jérémie Szeftel The resolution of the bounded L2 curvature conjecture in General Relativity (Part 4)

In order to control locally a space-‐time which satisfies the Einstein equations, what are the minimal assumptions one should make on its curvature tensor? The bounded L2 curvature conjecture roughly asserts that one should only need L2 bounds of the curvature tensor on a given space-‐like hypersurface. This conjecture has its roots in the remarkable developments of the last twenty years centered around the issue of optimal well-‐posedness for nonlinear wave equations. In this context, a corresponding conjecture for nonlinear wave equations cannot hold, unless the nonlinearity has a very special nonlinear structure. I will present the proof of this conjecture, which sheds light on the specific null structure of the Einstein equations. This is joint work with Sergiu Klainerman and Igor Rodnianski. These lectures will start from scratch and require no specific background.

We
will focus in our lectures on the following : 1. J-complex discs in
almost complex manifolds : general properties. Linearization and
compactness. Gromov’s method : the Fredholm alternative for the d-bar
operator. Attaching a complex disc to a Lagrangian manifold.
Application : exotic symplectic structures. Hulls of totally real
manifolds : Alexander’s theorem. 2. Real surfaces in (almost) complex
surfaces. Filling real 2-spheres by a Levi-flat hypersurface (Bedford
-Gaveau-Gromov theorem). Some applications. Symplectic and contact
structures. Reeb foliation and the Weinsten conjecture. Hofer’s proof of
the Weinstein conjecture. 3. J-complex lines and hyperbolicity. The KAM
theory and Moser’s stability theorem for entire J-complex curves in
tori. Global deformation and Bangert’s theorem. Mot(s) clés libre(s) : mathématiques, Grenoble, école d'été, institut fourier, summer school, feuilletages, COURBES PSEUDOHOLOMORPHES

I will explain how one can formulate and formalize the Gupta Bleuler framework for the Quantization of the electromagnetic field in an algebraic manner so that it works on globally hyperbolic space times. I will then discuss a construction of physical representations that works without the "spectral gap assumption" in the case of absense of zero energy resonances. These can be excluded by topologocial restrictions at infinity. This is based on joint work with Felix Finster.

Ce film présente “Flore de Lorraine”, table énigmatique à la marqueterie représentant un paysage allégorique de la Lorraine, commandée en automne 1893 à Emile Gallé et offerte au Tsar Alexandre III à l’occasion de la signature de l’alliance franco-russe.La table du Tsar raconte, en compagnie de conservateurs et restaurateurs du musée de l’Ermitage, d’historiens lorrains, de botanistes et biographes de Gallé, l’histoire de cet exceptionnel objet d’art conçu et fabriqué dans l’urgence par le célèbre artiste de l’Art Nouveau, ses collaborateurs et artisans, en seulement trois semaines.
