摘要:

In this paper, we consider the short time classical solution to a simplified hydrodynamic flow modeling incompressible, nematic liquid crystal materials in R3. We establish a criterion for possible breakdown of such solutions at a finite time. More precisely, if (u, d) is smooth up to time T provided that ∫0T║∇×u(t,·)║BMO(R3) + ║∇d(t,·)║L4(R3)8dt < ∞.
