Black holes play a central role in general relativity and astrophysics. The problem of proving the dynamical stability of the Kerr black hole spacetime, which is describes a rotating black hole in vacuum, is one of the most important open problems in general relativity.
Following a brief introduction to the evolution problem for the
Einstein equations, I will give some background on geometry of the Kerr spacetime. The
analysis of fields on the exterior of the Kerr black hole serve as important model problems for the black hole stability problem. I will discuss some of the difficulties one encounters in analyzing waves in the Kerr exterior
and how they can be overcome. A fundamentally important as
pect of geometry and analysis in the Kerr spacetime is the fact that it is algebraically special, of Petrov type D, and therefore admits a Killing spinor of valence 2. I will introduce the 2 spinor and related formalisms which can be used to see how this structure leads to the Carter constant and the Teukolsky system. If there is
time, I will discuss in this context some new conservation laws for fields of non zero spin. Mot(s) clés libre(s) : mathématiques, Grenoble, école d'été, General Relativity, institut fourier, summer school, asymptotic analysis

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. Mot(s) clés libre(s) : 1891, 1893, Alexandre III, Allemagne, alliance franco-russe, alliance germano-austro-italienne, annexion allemande, Art Nouveau, botanique, ébénisterie d’art, Ecole de Nancy, Emile Gallé, esthétique, flore, France, Guillaume II, histoire de l’art, image d
