Abstract

The paper investigates the existence and upper semicontinuity of uniform attractors of the perturbed non-autonomous Kirchhoff wave equations with strong damping and supercritical nonlinearity: uttΔut(1+ϵu2)Δu+f(u)=g(x,t)u_{tt}-\Delta u_{t}-(1+\epsilon\|\nabla u\|^{2})\Delta u+f(u)=g(x,t), where ϵ[0,1]\epsilon\in [0,1] is a perturbed parameter. It shows that when the nonlinearity f(u)f(u) is of supercritical growth p:N+2N2=p<p<p=N+4(N4)+p: \frac{N+2}{N-2}=p^*<p<p^{**}=\frac{N+4}{(N-4)^+}: (i) the related evolution process has a compact uniform attractor A\ls\e\mathcal{A}_\ls^\e for each ϵ[0,1]\epsilon\in [0,1]; (ii) the family of uniform attractor A\ls\e\mathcal{A}_\ls^\e is upper semicontinuous on the perturbed parameter ϵ\epsilon in the sense of partially strong topology.
