SUMMARY:London analysis seminar: Arianna Giunti (Imperial) — Quantitative
  homogenization for interacting particle systems
DESCRIPTION:Quantitative homogenization for interacting particle systems\nW
 e are interested in the bulk diffusion matrix A associated to a class of i
 nteracting particle systems in R^d. The models that we consider are revers
 ible with respect to the Poisson measures and are of non-gradient type. Re
 lying on the recent progress in quantitative stochastic homogenization for
  elliptic PDEs\, we prove that finite-volume approximations of A converge 
 at an algebraic rate. Furthermore\, we show that A is smooth in the densit
 y of particles and characterize its derivatives. This talk is based on joi
 nt works with C. Gu (NYU Shanghai)\, J.-C. Mourrat (ENS Lyon) and M. Nitzs
 chner (NYU Courant).\nLondon analysis and probability seminar homepage
