We establish a general result about (H2(Ω))2∩V-boundedness of invariant sets for the associate evolution process. Then, as a consequence, we deduce that, under adequate assumptions, the pullback attractors of the non-autonomous 2D Navier–Stokes equations are bounded not only in V but also in (H2(Ω))2.application/pdfengAtribución-NoComercial-SinDerivadas 4.0 Españahttp://creativecommons.org/licenses/by-nc-nd/4.02D-Navier-Stokes equationsPullback attractorsInvariant setsH2-regularityinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/openAccess10.1016/j.na.2011.04.063https://idus.us.es/xmlui/handle/11441/25931
