The JEDP 2020 conference will take place in Obernai, Monday June 8th — Friday June 12th 2020. Save the date!

The « Journées Équations aux Dérivées Partielles » is the annual conference of the CNRS groupement de recherche « Analyse des équations aux dérivées partielles ».

The  JEDP 2019 conference took place Monday June 3rd — Friday June 7th 2019 in Obernai (Alsace), at the VVF Villages, where all participants were accommodated.

Article « Ces mathématiciens du monde entier préparent l’avenir », Dernières Nouvelles d’Alsace (June 8th, 2019).

Lecture (6h)

Scott Armstrong (New York University)
« Quantitative stochastic homogenization »

Abstract: In this course I will discuss large-scale asymptotics of solutions of elliptic equations (in divergence form) with random coefficients. This is closely related to the behavior of reversible diffusions in random environments, since random elliptic operators are generators of such diffusions. We will focus on identifying the optimal rate of convergence for homogenization and ultimately describe the law of the fluctuations of solutions. Our approach involves renormalization arguments in which we progressively « coarsen the coefficient field » over larger and larger scales and combines this with ideas from elliptic regularity. Time permitting, I will discuss adaptations of these ideas to the homogenization of the kinetic Fokker-Planck equation, which is related to hypoelliptic diffusions in random media.
