具有热效应的双折射液晶流动的整体解

Global solution to the nematic liquid crystal flows with heat effect

Dongfen Bian, Yao Xiao

摘要:

本文研究了有界区域$Ω\subset\mathbb{R}^N$($N=2, 3$)中温度相关的不可压缩液晶流动。根据Danchin在[J. Math. Fluid Mech.,2006]中,利用局部化方法恢复了变粘性斯托克斯方程的最大正则性,首先证明了强解的局部存在性,然后在初始值为平凡平衡态附近的一个足够小的扰动的条件下,将其推广到全局解.本文还推广了Hu-Wang在[Commun.数学物理,[2010]非线性方程组。

英文摘要:

The temperature-dependent incompressible nematic liquid crystal flows in a bounded domain $Ω\subset\mathbb{R}^N$ ($N=2, 3$) are studied in this paper. Following Danchin's method in [J. Math. Fluid Mech., 2006], we use a localization argument to recover the maximal regularity of Stokes equation with variable viscosity, by which we first prove the local existence of strong solution, then extend it to a global one provided that the initial data is a sufficiently small perturbation around the trivial equilibrium state. This paper also generalizes Hu-Wang's result in [Commun. Math. Phys., 2010] to the non-isothermal case.
