The function β"(t) depends on a parameter ε, β"(t) "!0 −→ 0. We will prove, under suitable assumptions, local and global well posedness (using the uniform sectorial operators theory), the existence and regularity of pullback attractors {A"(t) : t ∈ R}, uniform bounds for these pullback attractors, characterization of these pullback attractors and their upper and lower semicontinuity at ǫ = 0.application/pdfengAtribución-NoComercial-SinDerivadas 4.0 Españahttp://creativecommons.org/licenses/by-nc-nd/4.0Non-autonomous damped wave equationExistence and structure of the pullback attractorLower and upper semicontinuityinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/openAccess10.1016/j.na.2010.11.032https://idus.us.es/xmlui/handle/11441/23632
