二维液晶流模型的有限维全局吸引子

Finite--dimensional global attractor for a system modeling the 2D nematic liquid crystal flow

Maurizio Grasselli, Hao Wu

摘要:

我们考虑一个二维系统,通过适当耦合的平均分子取向的传输-反应扩散方程的斯托克斯方程模型的液晶流动。这个系统已被提出作为一个合理的近似著名的Ericksen-Leslie系统。利用以前的适定性结果和证明适当的耗散估计,在这里,我们证明了系统赋予周期边界条件是一个耗散的动力系统具有一个光滑的全球吸引子的有限分形维数。

英文摘要:

We consider a 2D system that models the nematic liquid crystal flow through the Navier--Stokes equations suitably coupled with a transport-reaction-diffusion equation for the averaged molecular orientations. This system has been proposed as a reasonable approximation of the well-known Ericksen--Leslie system. Taking advantage of previous well-posedness results and proving suitable dissipative estimates, here we show that the system endowed with periodic boundary conditions is a dissipative dynamical system with a smooth global attractor of finite fractal dimension.
