三维Ericksen-Leslie系统的奇点

On singularities of Ericksen-Leslie system in dimension three

Tao Huang, Peiyong Wang

摘要:

本文研究三维液晶流动Ericksen-Leslie方程组的初边值问题和边值问题。构造了两个有限时刻奇异性的例子。第一个例子是构造在一个特殊的轴对称类与适当的轴对称初始和边界数据,而第二个例子是构造的初始数据与小能量,但非平凡的拓扑结构。利用一维Poiffille流构造了系统的最大值原理的一个反例。

英文摘要:

In this paper, we consider the initial and boundary value problem of Ericksen-Leslie system modeling nematic liquid crystal flows in dimension three. Two examples of singularity at finite time are constructed. The first example is constructed in a special axisymmetric class with suitable axisymmetric initial and boundary data, while the second example is constructed for an initial data with small energy but nontrivial topology. A counter example of maximum principle to the system is constructed by utilizing the Poiseuille flow in dimension one.
