摘要 利用了无穷维动力系统吸引集和吸引子概念以及挤压性质,证明了两个相同的二维Navier -Stokes方程在高频耦合条件下可达到完全同步化.在数学理论上定性解释了无穷维动力系统的 同步化现象.证明方法不同于通常的Lyapunov函数方法和近似线性方法.这两个系统的同步化可 能解释在地球气候系统中太平洋和大西洋区域之间的关系. By using the concepts of absorbing sets, attractor and squeezing properties, the occurrence of complete synchronization of two high frequency coupled 2D Navier-Stokes equations is proved. Synchronization phenomenon of infinite-dimensional system is illustrated qualitatively. The method is different from Lyapunov function method and approximate linearity method. Synchronization of these two systems may illustrate a relationship between the Atlantic and Pacific sectors of the Earth' s climate system.
