本文在3维薄区域Ωε=w×(0,E)上讨论Navier—Stokes方程吸引子的Hausdorff维数.首先对六种不同空间边界条件,分3类给出吸引子维数估计;然后针对其中一种做进一步讨论,得到更精细估计,使得吸引子维数与区域厚度£的依赖关系明显化.
We estimate the Hausdorff dimension of the attractor for Navier-Stokes equations on 3-dimensional thin domain wε with six kinds of boundary conditions. Further we show the relation between the dimension of the attractor and thickness ε for one case.
