Caraballo, Tomás; Kloeden, P. E. Non-autonomous attractors for integro-differential evolution equations. (English) Zbl 1185.45016 Discrete Contin. Dyn. Syst., Ser. S 2, No. 1, 17-36 (2009). In the first part of this paper, the authors provide sufficient conditions for the existence of pullback attractors for so-called multivalued non-autonomous dynamical systems (MNDS). The pullback attractors are defined here with respect to a universe of subsets of the state space with sub-exponential growth. Next they consider the following evolution equation \[ \frac{dy}{dt}=Ay+f(t,y_t), \]where \(A\) is the generator of a \(C_0\) contraction semigroup \((e^{At})_{t\geq 0}\) on a separable Banach space \((H,\|\cdot\|)\) such that \[ \|e^{At}x\|\leq\|x\|e^{-\alpha t},\;\;\text{for some } \alpha>0\;\;\text{and every } t\geq 0, \]the operators \(e^{At}\) are compact for \(t>0\) and \(y_t:(-\infty,0]\to H\) is defined as \(y_t(s)=y(t+s)\), \(s\in (-\infty,0]\). It is proved that under suitable assumptions on \(f\) the initial value problem \((IVP)_{t_0,\varphi}\) for the above equation possesses a mild solution in the function space \(C_{\gamma}=\{u\in C((-\infty,0];H):\;\lim_{\tau\to -\infty}u(\tau) e^{\gamma\tau}\,\text{exists}\}\), where \(\gamma>\alpha\).Moreover, it is proved that under suitable assumptions an MNDS generated by the above equation has a pullback \(\mathcal D\)-attractor \(A\) in the suitable set \(C(C_{\gamma})\).As examples the authors consider an ordinary integro-differential equation and an integro-differential reaction-diffusion equation.
