广义Ericksen-Leslie系统的Parodi关系、适定性和稳定性

On the General Ericksen-Leslie System: Parodi's Relation, Well-posedness and Stability

Hao Wu, Xiang Xu, Chun Liu

摘要:

本文研究了Parodi关系在模拟双折射液晶流动的一般Ericksen-Leslie系统的适定性和稳定性中的作用。首先,在Parodi关系下,通过适当的能量变分方法,给出了Ericksen-Leslie系统的形式化物理推导,其中我们可以区分诱导弹性应力的保守/耗散部分。其次,在粘性$μ_4$足够大的假设下,证明了Ericksen-Leslie系统的全局适定性和长时间行为.最后,在Parodi关系下,我们证明了Ericksen-Leslie系统在局部能量极小点附近的全局适定性和Lyapunov稳定性。本文还讨论了Parodi关系与Ericksen-Leslie系统线性稳定性之间的关系。

英文摘要:

In this paper we investigate the role of Parodi's relation in the well-posedness and stability of the general Ericksen-Leslie system modeling nematic liquid crystal flows. First, we give a formal physical derivation of the Ericksen-Leslie system through an appropriate energy variational approach under Parodi's relation, in which we can distinguish the conservative/dissipative parts of the induced elastic stress. Next, we prove global well-posedness and long-time behavior of the Ericksen-Leslie system under the assumption that the viscosity $μ_4$ is sufficiently large. Finally, under Parodi's relation, we show the global well-posedness and Lyapunov stability for the Ericksen-Leslie system near local energy minimizers. The connection between Parodi's relation and linear stability of the Ericksen-Leslie system is also discussed.
