The relationship between pullback, forward and global attractors of nonautonomous dynamical systems. (English) Zbl 1054.34087
The authors study and compare various types of attractors for nonautonomous dynamical systems involving a cocycle state space driven by an autonomous dynamical system on a compact state space. In particular, they give conditions for a uniform pullback attractor to form a global attractor of the associated autonomous skew-product semi-dynamical system. They generalize Zubov’s theorem on the characterization of the asymptotic stability of a compact set with respect to an α-condensing semi-dynamical system. The results are illustrated by several examples – in particular by a nonautonomous Navier-Stokes equation – that are generated by differential equations on a Banach space with a uniform dissipative structur induced by a monotone operator.
