$\mathbb R^3$中带Q张量的LCD系统的正则性问题

Regularity problem for the nematic LCD system with Q-tensor in $\mathbb R^3$

Mimi Dai

摘要:

本文研究了具有局域组态的液晶模型的正则性问题。经典的Prodi-Serrin条件是否意味着这个模型的正则性是一个悬而未决的问题。应用波数分裂方法,我们证明了在某些推广的Beale-Kato-Majda条件下,解不爆破。这个正则性准则自动地意味着经典的Prodi-Serrin或Beale-Kato-Majda条件可以防止解的爆破。

英文摘要:

We study the regularity problem of a nematic liquid crystal model with local configuration represented by Q-tensor in three dimensions. It was an open question whether the classical Prodi-Serrin condition implies regularity for this model. Applying a wavenumber splitting method, we show that a solution does not blow-up under certain extended Beale-Kato-Majda condition solely imposed on velocity. This regularity criterion automatically implies that the classical Prodi-Serrin or Beale-Kato-Majda condition prevents blow-up of solutions.
