摘要：
本文研究了二维不可压缩流体纳维-斯托克斯方程（NSE）中确定模式性质与两种用于连续数据同化应用的过滤算法的重构性质之间的相互关系。这两种性质作为更一般现象“自同步交织”的表现形式而实现。证明了这一概念是渐近奴役的一种逻辑更强形式，其特征是存在有限个确定模式。特别是，这种更强形式被证明可以导致直接替换滤波器和 nudging 滤波器从连续数据同化（CDA）中收敛，然后进一步被用来证明这些滤波器的收敛性意味着 2D NSE 具有有限个确定模式。本文的主要成就是开发了一种新的概念框架，即自同步交织，从而严格建立了这些 CDA 滤波器中确定模式性质与同步现象之间的精确相互关系。理论结果随后通过数值实验得到补充，以确认定理的结论。
英文摘要：
This article studies the interrelation between the determining modes property in the two-dimensional (2D) Navier-Stokes equations (NSE) of incompressible fluids and the reconstruction property of two filtering algorithms for continuous data assimilation applied to the 2D NSE. These two properties are realized as manifestations of a more general phenomenon of "self-synchronous intertwinement." It is shown that this concept is a logically stronger form of asymptotic enslavement, as characterized by the existence of finitely many determining modes in the 2D NSE. In particular, this stronger form is shown to imply convergence of the direct-replacement filter and the nudging filter from continuous data assimilation (CDA), and then subsequently invoked to show that convergence in these filters implies that the 2D NSE possesses finitely many determining modes. The main achievement of this article is to therefore to develop a new conceptual framework, that of self-synchronous intertwinement, through which the precise inter-relationship between the determining modes property and synchronization phenomenon in these CDA filters is rigorously established and made decisively clear. The theoretical results are then complemented by numerical experiments that confirm the conclusions of the theorems.
