临界Besov空间中三维密度相关液晶流的整体适定性

Global well-posedness for the 3-D density-dependent liquid crystal flows in the critical Besov spaces

Xiaoping Zhai, Yongsheng Li, Wei Yan

摘要:

本文在临界Besov空间中证明了三维密度相关液晶流的局部适定性,初始数据不需要作小密度变化的假设。此外,如果初始密度足够接近于一个正的常数,并且液晶取向场和初始速度场的水平分量的临界Besov范数与初始速度场的垂直分量的临界Besov范数相比多项式小,则系统具有唯一的全局解.

英文摘要:

In this paper, we prove the local well-posedness of 3-D density-dependent liquid crystal flows with initial data in the critical Besov spaces, without assumptions of small density variation. Furthermore, if the initial density is close enough to a positive constant and the critical Besov norm of the liquid crystal orientation field and the horizontal components of the initial velocity field polynomially small compared with the critical Besov norm to the veritcal component of the initial velocity field, then the system has a unique global solution.
