Query: On diffusive 2D Fokker-Planck-Navier-Stokes systems   We study models kinetic models of polymeric fluids. We introduce a notion of
solutions which is based on moments of polymeric distributions. We prove global
existence and uniqueness of a large class of initial data for diffusive systems
of kinetic equations coupled to fluid equations. As a corollary, we obtain a
rigorous derivation of Oldroyd-B closure. We also prove decay of free energy
for all the systems considered.
