This survey concerns attractors of infinite-dimensional dissipative dynamical systems.
After an introduction, in Section 2 the main definitions and results about global attractors, their dimension and their robustness are presented. Section 3 deals with exponential attractors and inertial manifolds. Section 4 concerns uniform attractors and pullback attractors and pullback attractors of nonautonomous systems, and finite-dimensional reductions of nonautonomous systems are described.
The main section is Section 5 about dissipative PDEs on unbounded domains. The dynamics of those PDEs is purely infinite-dimensional, in general, and, hence, does not possess any finite-dimensional reduction. Moreover, interactions between spatial and temporal chaotic modes can lead to so-called space-time chaos with infinite Lyapunov dimension and infinite topological entropy.
Finally, generalizations to ill-posed problems (by means of trajectory attractors) are given in Section 6.
