Abstract
We consider the attractors for the two-dimensional nonautonomous Navier-Stokes equations in some unbounded domain Ω with nonhomogeneous boundary conditions. We apply the so-called uniformly ω-limit compact approach to nonhomogeneous Navier-Stokes equation as well as a method to verify it. Assuming f∈Lloc2((0,T);L2(Ω)), which is translation compact and φ∈Cb1(ℝ+;H2(ℝ1×{±L})) asymptotically almost periodic, we establish the existence of the uniform attractor in H1(Ω).
