Abstract
In this chapter we derive dimension and entropy estimates for invariant sets and global \(\mathcal{B}\)-attractors of cocycles in non-fibered and fibered spaces. A version of the Douady-Oesterlé theorem will be proven for local cocycles in an Euclidean space and for cocycles on Riemannian manifolds. As examples we consider cocycles, generated by the Rössler system with variable coefficients. We also introduce time-discrete cocycles on fibered spaces and define the topological entropy of such cocycles. Upper estimates of the topological entropy along an orbit of the base system are given which include the Lipschitz constants of the evolution system and the fractal dimension of the parameter dependent phase space.
