Colloquium @ CEREMADE

Description

Our colloquium takes place on the first Tuesday of each month from 15:30 to 16:30, usually in room A709.


A renowned expert (being an excellent speaker as well) visits us for an afternoon and gives a panorama of one of her research areas. The talk is meant to be accessible to all members of the lab, including PhD students in analysis, game theory, probability and statistics. Ideally, it should start gently with an historical background on the problem and an overview of the main questions and applications, keeping a non technical style during at least the first half of the talk. Of course it is also nice to have a part with more mathematical details: the most appreciated colloquia were those in which the speaker succeeded to develop a nice technical idea or an elegant argument that everyone should know.


Food and drinks are served after the event, usually in Espace 7!


If you know good speakers whom you would love to hear, do not hesitate to suggest their names to the two organizers: Justin Salez and Cristina Toninelli.

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


Abstract: 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.
