摘要
This paper is concerned with a generalized 2D parabolic equation with a nonautonomous perturbation -Delta u(t) + alpha(2)Delta(2)u(t)+ mu Delta(2)(u) + del.(F) over bar + B(u,u) = is an element of g(x,t) Under some proper assumptions on the external force term g, the upper semicontinuity of pullback attractors is proved. More precisely, it is shown that the pullback attractor {A(is an element of)(t)}(t is an element of R) of the equation with is an element of> 0 converges to the global attractor A of the equation with is an element of- 0.
