Global Well-Posedness of Strong Solutions of Doi Model with Large Viscous Stress

  • Joonhyun LaEmail author


We study models of dilute rigid rod-like polymer solutions. We establish the global well-posedness of the Doi model for large data and for arbitrarily large viscous stress parameter. The main ingredient in the proof is the fact that the viscous stress adds dissipation to high derivatives of velocity.
