Titre : Speed of propagation for the boson star equation

Résumé : We will consider a non linear equation describing a large group of gravitating bosons that form a boson star. After briefly discussing the well-posedness of the equation, we will study some dispersive properties of the solution, in particular how fast it propagates and its maximal and minimal velocities of propagation. These results are a joint work with Sébastien Breteaux and Jérémy Faupin.

Titre : The 2D Stochastic Heat Equation and related critical models

Résumé : We present recent progress on a class of "critical" models in two space dimensions, including the Stochastic Heat Equation, the Kardar-Parisi-Zhang (KPZ) equation and a key model in statistical mechanics: the directed polymer in random environment. These developments have led to the construction of a new universal object, the critical 2D Stochastic Heat Flow, which provides a non-trivial solution for the ill-posed 2D Stochastic Heat Equation. The aim of the talk is to give a broad overview of these topics and to highlight some of the key ideas that have driven recent breakthroughs in the field.
