Chaos and chaotic fluid mixing

Very simple mathematical equations can give rise to surprisingly complicated, chaotic dynamics, with behavior that is sensitive to small deviations in the initial conditions. We  illustrate this with a single recurrence  equation that can be  easily simulated, and with mixing in simple fluid flows.

Factorisation de matrices

Ce qui suit est un court abrégé sur le thème de la factorisation de matrices. Nous expliquerons pourquoi ce concept très simple mène à des cheminements de pensée étonnamment profonds et trouve dans la physique théorique moderne d’importantes applications.
