"WebApplying the tools The so-called ‘evolution rule’ in dynamical system theory is largely deterministic, meaning that for a specific period of time only, one future state follows the current state. However, some systems are more chaotic in that random external events can actually influence the outcome within systems. " - Dynamical evolution of quantum states
