The purpose of this article is to study the hitting times for random dynamical systems. For general systems we give a lower bound in terms of the local dimension. For fast mixing systems we obtain an equality. Moreover, under a power law decay of correlations we obtain lower and upper bounds of the hitting times for absolutely continuous stationary measures.
In this paper we study the distributions of hitting and return times for observations of dynamical systems. We apply the results to get an exponential law for the distributions of hitting and return times for rapidly mixing random dynamical systems. In particular, this allows us to obtain an exponential law for random expanding maps, random circle maps expanding on average and randomly perturbed dynamical systems.
Berzelius failed to make use of Faraday's electrochemical laws in his laborious determination of equivalent weights.
