摘要:
本文研究了双轴和单轴$Q$-张量在一般Landau-de Gennes能量密度下的Beris-Edwards系统,该能量密度依赖于四个非零弹性常数。我们证明了单轴$Q$-张量的Beris-Edwards系统强解在最大时间之前的存在性。此外,我们证明了双轴$Q$-张量的Beris-Edwards系统强解在其最大存在时间之前光滑收敛到单轴$Q$-张量的Beris-Edwards系统的解。
英文摘要:
In this paper, we investigate the Beris-Edwards system for both biaxial and uniaxial $Q$-tensors with a general Landau-de Gennes energy density depending on four non-zero elastic constants. We prove existence of the strong solution of the Beris-Edwards system for uniaxial $Q$-tensors up to a maximal time. Furthermore, we prove that the strong solutions of the Beris-Edwards system for biaxial $Q$-tensors converge smoothly to the solution of the Beris-Edwards system for uniaxial $Q$-tensors up to its maximal existence time.
