Global Well Posedness for a Q-tensor Model of Nematic Liquid Crystals
Journal of Mathematical Fluid Mechanics(2022)
摘要
In this paper, we prove the global well posedness and the decay estimates for a
$${\mathbb {Q}}$$
-tensor model of nematic liquid crystals in
$$\mathbb {R}^N$$
,
$$N \ge 3$$
. This system is a coupled system by the Navier–Stokes equations with a parabolic-type equation describing the evolution of the director fields
$${\mathbb {Q}}$$
. The proof is based on the maximal
$$L_p$$
–
$$L_q$$
regularity and the
$$L_p$$
–
$$L_q$$
decay estimates to the linearized problem.
