Geometric-Analityc inequalities (and applications to PDEs)

Résumé : (Masquer les résumés)
Many of the most important results in mathematics are based on some inequality, of geometric or analytic nature. On the other hand, this separation between geometry and analysis is not sharp and the most intriguing inequalities are indeed the ones that have a mixed nature and enhance the interplay of the two realms. Moreover, many apparently purely geometric inequalities have some powerful functional counterpart, like for instance the Isoperimetric Inequality and Sobolev Inequality. I will try to give some general overview on geometric-analytic inequalities and will concentrate on one of them, precisely the Brunn-Minkowski inequality, an apparently geometric inequality which is at the core of modern convex geometry, and on its functional counterpart, the Borell-Brascamp-Lieb inequality. And also possibly show some applications to PDEs.

Les oscillations de Joseph Fourier

Résumé : (Masquer les résumés)
Joseph Fourier a vécu une vie mouvementée entre révolution française, expédition en Egypte, perçage de la route du Lautaret et académie des sciences. Il est surtout connu pour ses travaux en physique (équation de la chaleur, première discussion sur l'influence de l'homme sur l'effet de serre à l'échelle de la planète...) et en mathématique (la transformation qui porte son nom étant présente dans de très nombreuses applications, dont les fichiers mp3 et les images jpeg). Dans cet exposé, nous présenterons sa vie et son oeuvre et nous aborderons la transformation de Fourier à travers des images, des sons et un piano qui parle.
