SUMMARY:Andrea Bondesan (Paris Descartes University): Diffusion limits of t
 he Boltzmann multi-species equation through perturbation of hypocoercivity
DESCRIPTION:Andrea Bondesan: We discuss the rigorous derivation of hydrodyn
 amic limits of the Boltzmann multi-species equation\, when the Mach and Kn
 udsen numbers vanish at the same rate. Solutions of the kinetic equations 
 are constructed as fluctuations around local non-equilibrium Maxwellians\,
  whose physical observables solve the limiting macroscopic model of intere
 st. A general hypocoercive formalism is used to develop a uniform (with re
 spect to the small diffusion parameter) Cauchy theory for this perturbativ
 e setting and an application to derive the Maxwell-Stefan cross-diffusion 
 system is presented.\n\nhttps://andreabondesan.wordpress.com/\n\n\nSémina
