Abstract
Many complex systems are a combination of deterministic and stochastic dynamics. Some systems can be understood by applying random perturbation theory to the underlying deterministic dynamics. However, generally the randomness may not necessarily be small and could consist of any type of stochasticity. Here, we consider a simplest case where only two types (i.e., dichotomic) of dynamics are generated randomly in time, and explore in (1) a simple piecewise-linear random system where either an expanding or contracting map is selected at each time iteration, and (2) a system of coupled rotors kicked with temporally correlated random sequences. In both examples, we illustrate analytically and numerically their rich dynamical behaviour.
