Matthias Hieber, Manuel Nesensohn, Jan Prüss, Katharina Schade

摘要:

考虑(简化的)Leslie-Erickson模型,用于在n > 1 $. This article develops a complete dynamic theory for these equations, analyzing the system as a quasilinear parabolic evolution equation in an $ L_p-L_q$-设置的有界域$Ω\subset \mathbb{R}^n$中的双折射液晶的流动。首先证明了该方程局部强解的存在性。这个解决方案扩展到一个全球性的强解,提供的初始数据是接近平衡或解决方案是最终有界的基础状态空间的自然规范。在这种情况下,解指数收敛到一个平衡点。此外,解决方案是真正的解析,在时间和空间。

英文摘要:

Consider the (simplified) Leslie-Erickson model for the flow of nematic liquid crystals in a bounded domain $Ω\subset \mathbb{R}^n$ for n > 1$. This article develops a complete dynamic theory for these equations, analyzing the system as a quasilinear parabolic evolution equation in an $L_p-L_q$-setting. First, the existence of a unique local strong solution is proved. This solution extends to a global strong solution, provided the initial data are close to an equilibrium or the solution is eventually bounded in the natural norm of the underlying state space. In this case the solution converges exponentially to an equilibrium. Moreover, the solution is shown to be real analytic, jointly in time and space.
