Abstract

In this paper, under some appropriate assumptions, we prove the existence of the minimal time-dependent pullback DσHt\mathcal D_{\sigma}^{\mathcal{H}_{t}}-attractors ADσHt{\mathcal{A}}_{\mathcal D_{\sigma}^{\mathcal{H}_{t}}} for the non-autonomous nonlocal diffusion equations in time-dependent space Ht(Ω)\mathcal{H}_{t}(\Omega). Next, in same phase space, using a priori estimate and energy methods we establish the existence of time-dependent pullback attractors {Aξ(t)}tR\left\{A_{\xi}(t)\right\}_{t \in \mathbb R} and the upper semicontinuity of {Aξ(t)}tR\left\{A_{\xi}(t)\right\}_{t \in \mathbb R} and the global attractor AA of the equation with ξ=0\xi = 0, that is, limξ0+distHt(Aξ(t),A)=0. \lim_{\xi \rightarrow 0^{+}} \operatorname{dist}_{\mathcal H_{t}}\left(A_{\xi}(t), A \right)=0.
