摘要
该文主要考虑一类非线性项具有临界指数增长的非自治非经典扩散方程生成的拉回吸引子在H_01(Ω)空间中的上半连续性.具体来讲,该文讨论了方程(1.1)生成的拉回吸引子{A_ε(t)}_(t∈R)(ε∈[0,1]),对任意的[a,b]R,ε_0∈[0,1]满足limε→ε_0 sup t∈[a,b] dist_H_01(Ω)(A_ε(t),A_(ε_0)(t))=0,并且集合∪_(t∈[a,b])∪_(ε∈[0,1])A_ε(t)是H_01(Ω)中的紧集.
This paper is concerned with upper semicontinuity of pullback attractors,for a nonautonomous nonclassical diffusion equation with critical nonlinearity.In particular,under some proper assumptions,we prove that,the pullback attractor {A_ε(t)}_(t∈R) of equation(1.1)with ε∈[0,1]satisfies that for any[a,b]R and ε_0 ∈[0,1],limε→ε_0 sup t∈[a,b] dist_(H_01)(A_ε(t),A_ε_0(t)) = 0and ∪_(t∈[a,.b])∪_(ε∈[0,1]) A_ε(t) is precompact in H_0-1(Ω).
