Andras Vasy - Microlocal analysis and wave propagation (Part 3)

In these lectures I will explain the basics of microlocal analysis, emphasizing non elliptic problems, such as wave propagation, both on manifolds without boundary, and on manifolds with boundary. In the latter case there is no `standard' algebra of differential, or pseudodifferential, operators; I will discuss two important frameworks: Melrose's totally characteristic, or b, operators and scattering operators. Apart from the algebraic and mapping properties, I will discuss microlocal ellipticity, real principal type propagation, radial points and generalizations, as well as normally hyperbolic trapping. The applications discussed will include Fredholm frameworks (which are thus global even for non elliptic problems!) ...

Jean-Pierre Demailly - Kobayashi pseudo-metrics, entire curves and hyperbolicity of algebraic varieties (Part 4)

We will first introduce the basic concepts pertaining to Kobayashi pseudo-distances and hyperbolic complex spaces, including Brody’s theorem and the Ahlfors-Schwarz lemma. One of the main goals of the theory is to understand conditions under which a given algebraic variety is Kobayashi hyperbolic. This leads to the introduction of jet spaces and jet metrics, and provides a strong link between the existence of entire curves and the existence of global algebraic differential equations.

Jdev2017 : T8_A10 (2e Partie) : Atelier "Portage D'Un Code Sous Mpi"

Cet atelier va permettre de montrer une manière de porter un code séquentiel résolvant un problème simple de calcul scientifique, dans un environnement parallèle, en utilisant les primitives de communication MPI. On s’attachera à montrer l’importance de la communication et de la synchronisation des machines dans le cas d’une résolution synchrone ou asynchrone.Plus d'informations sur l'atelier
