Oseen-Frank模型液晶流解的整体存在性

Global existence of solutions of the Liquid Crystal flow for the Oseen-Frank model

Min-Chun Hong, Zhouping Xin

摘要:

在本文的第一部分中,我们建立了著名的Oseen-Frank模型的液晶(梯度)流的整体解的存在性。液晶流是流体动力学理论中Ericksen-Leslie系统方程的原型,并将调和映射的热流推广到2-球。Ericksen-Leslie系统是与液晶流耦合的Navier-斯托克斯方程的系统。在本文的第二部分中,我们还证明了一般Oseen-Frank模型的Ericksen-Leslie系统在$\Bbb R^2$中整体解的存在性。

英文摘要:

In the first part of this paper, we establish global existence of solutions of the liquid crystal (gradient) flow for the well-known Oseen-Frank model. The liquid crystal flow is a prototype of equations from the Ericksen-Leslie system in the hydrodynamic theory and generalizes the heat flow for harmonic maps into the 2-sphere. The Ericksen-Leslie system is a system of the Navier-Stokes equations coupled with the liquid crystal flow. In the second part of this paper, we also prove global existence of solutions of the Ericksen-Leslie system for a general Oseen-Frank model in $\Bbb R^2$.
