This paper is devoted to the study of attractor of stochastic viscous Cahn-Hilliardequation driven by white noise, d((1-α)u-α△u)+(△2u-△f(u))dt=dW,(x, t)∈G×(t0,∞),(2) u(x, t)=0,(x, t)∈G×[t0,∞),on a bounded domain, where α, μ∈[0,1] are parameters. For any given μ∈(0,1], underreasonable assumptions, we first show that the problem has a stochastic global attractorAα,μ(ω) H2(G)∩H01(G), which pullback attracts every bounded deterministic setB H2(G)∩H01(G) and then prove that Aα,μ(ω) is supper semicontinuous in α. Finally,we study, for fixed α∈[0,1], the continuity of Aα,μ(ω) and its Morse decompositionswith μ, and obtain(i) Aα,μ(ω) and its Morse decompositions are supper semicontinuous in μ at μ=0.(ii) Aα,μ(ω) is lower semicontinuous in μ at μ=0. |
