研究周期边界条件下Navier—Stokes方程的长时间行为,利用正交分解法构造一个有限维解序列,证明了该解序列在长时间后无限逼近方程的整体吸引子,并且给出渐近吸引子的维数估计。
The long time behavior of the solution of Navier-Stokes equations with periodic boundary conditions is studied. A solution sequence is constructed by using orthogonal decomposition, which approaches to the global attractor of the equation in long time, and the dimentional estimation of the asymptotic attractor is given.
