摘要/Abstract

摘要：

该文研究了带弱阻尼Navier-Stokes方程解的长时间动力学行为. 在外力项及初值的适当假设条件下, 利用Galerkin方法证明了弱解的整体适定性及正则性, 并根据吸引子基本理论验证了拉回吸引子的存在性及收敛性.

关键词: 拉回吸引子, Navier-Stokes方程, 弱阻尼, 上半连续性

Abstract:

The long-time behavior of solution to Navier-Stokes equations with weak damping is studied in this paper. With some assumptions on the external force and initial datum, the global wellposedness and regularity of weak solution are proved by Galerkin method, and the existence and convergence of pullback attractors are established finally.

Key words: Pullback attractors, Navier-Stokes equations, Weak damping, Upper semicontinuity
