Abstract: This survey paper reviews recent developments concerning the existence of global weak solutions to Fokker-Planck equations with unbounded drift terms, and coupled Navier-Stokes-Fokker-Planck systems of partial differential equations, that arise in finitely extensible nonlinear elastic (FENE) type kinetic models of incompressible dilute polymeric fluids in the case of general noncorotational flow.

Keywords:  Existence of weak solutions, dilute polymer, kinetic theory, Navier-Stokes equation, Fokker-Planck equation.
