Abstract:

In this paper, the upper semi-continuity of pullback attractors for the 2D non-autonomous Navier-Stokes equations with weak damping and external force perturbation terms which describes the motion of fluid with weak damping was considered. By decomposition of process (semigroup) and some estimates, we obtained the pullback attractors Aε(t) of equation (1.1) with ε>0 converges to the global attractor A of equation (1.1) with ε=0 for any t∈R.

Key words: Navier-Stokes equation, Pullback attractors, Upper semi-continuity
