“…Concerning the 2D incompressible Navier-Stokes flows (f (t, u t ) = 0 in (1)) driven by non-homogeneous boundary conditions in regular domains, Miranville and Wang [27], [28] introduced a background flow to deal with the boundary conditions, and obtained the existence of the finite dimensional global attractor under the assumptions that ∂Ω ∈ C 3 and |∇ϕ| ∈ L ∞ (∂Ω). For the Lipschitz-like case, motivated by [27,28] and based on estimates on the Stokes problem in [13] and [32], Brown, Perry and Shen [3] introduced the background flow in Lipschitz-like domains and proved the existence of the finite (fractal) dimensional universal attractor. Using the theory of pullback attractors, Yang, Qin, Lu and Ma [39] deduced the existence and regularity of pullback attractors, based on the background flow in Lipschitz-like domains.…”
