SUMMARY:BZ Seminar in Analysis: David Gérard-Varet (Paris)
DESCRIPTION:A  popular model for suspensions of non-spherical particles in
  fluids is the so-called Doi model\, which couples a Stokes equation for t
 he fluid velocity u(t\,x) together with a transport equation for the distr
 ibution of particles  in space and orientation f(t\,x\,p). The Doi model 
 comes from a formal mean-field limit of a system of particles interacting 
 inside a Stokes flow. We will show in this talk that this formal limit is 
 not accurate and will rigorously derive a correction to the model\, under 
 natural assumptions on the initial distribution of the particles. This is 
 joint work with R. Höfer (Regensburg university).
