Abstract:
In this talk we discuss critical thresholds in
Fokker Planck type equations for polymers. For rigid
rod-like molecule of polymers, we investigate the
structure and classification of equilibrium
solutions of a 3D nonlinear Doi-Onsager equation
with the Maier-Saupe potential. It is shown that the
number and structure of equilibrium solutions hinge
on whether the intensity parameter crosses two
critical values. We then discuss global orientation
dynamics in terms of such critical intensity
parameters. Finally we investigate critical
thresholds on boundary conditions for a dumbbell
model with FENEE potential.
