|Titre||Propagation of chaos for large systems of interacting particles|
|Horaire||17:00 à 18:00|
This talk will introduce and explain some classical and more recent results on the mean field limit and propagation of chaos for systems of many particles, leading to Vlasov, McKean-Vlasov or macroscopic equations such as the vorticity formulation for the 2d Euler or Navier-Stokes systems. Large systems of interacting particles are very complex but also interplay with a large set of applications, from cosmology to the biosciences. Particles can actually represent a wide range of objects: galaxies in some cosmological models, ions or electrons in plasmas, bacteria or cells in biosciences, ``agents'' in economics or social sciences. A classical way of reducing the complexity of those large systems is through the derivation of appropriate limit equations, in particular with the so-called mean field limits.
