Fractions continues multidimensionnelles : dynamique, arithmétique et combinatoire

Abstract: (Hide abstracts)
Dans cette exposé, on montre comment donner une interprétation géométrique et dynamique à certains algorithmes de fraction continues multidimensionnelles; cela permet, en utilisant l'algorithme de Brun, de donner un modèle symbolique pour le flot des chambres de Weil.

Dispersion for the wave and the Schrödinger equations outside strictly convex obstacles

Abstract: (Hide abstracts)
We consider the linear wave equation and the linear Schrödinger equation outside a compact, strictly convex obstacle in Rd with smooth boundary. In dimension d=3 we show that the linear wave flow and the linear Schrödinger flow satisfy the dispersive estimates as in R3. For d> 3, if the obstacle is a ball, we show that there exists points where the dispersive estimates fail for both wave and Schrödinger equations.
