Existence of multiple noise-induced transitions in a Lasota-Mackey map
Posted on

The addition of stochastic noise to a deterministic dynamical system can induce dramatic qualitative changes in its behaviour. In one counterintuitive effect – termed noise induced order – the addition of noise to an already chaotic system can make its behaviour more

Network scientists rely on random graphs to model the behaviour of complex networks observed in social, technological, and biological systems. One common approach to such network modelling starts by measuring an empirical set of observables, and then builds an ensemble of random
