Strange Nonchaotic Attractors in Random Dynamical Systems [PDF]

open access: yesPhysical Review Letters, 2004
Whether strange nonchaotic attractors (SNAs) can occur typically in dynamical systems other than quasiperiodically driven systems has long been an open question. Here we show, based on a physical analysis and numerical evidence, that robust SNAs can be induced by small noise in autonomous discrete-time maps and in periodically driven continuous-time ...

Dynamical behaviors of stochastic local Swift-Hohenberg equation on unbounded domain

open access: yesJournal of Inequalities and Applications, 2016
In this paper, we first study the deterministic Swift-Hohenberg equation on a bounded domain. After obtaining some a priori estimates by the uniform Gronwall inequality, we prove the existence of an attractor by the Sobolev compact embeddings.

Random Attractor for Stochastic Wave Equation with Arbitrary Exponent and Additive Noise on $\mathbb{R}^n$ [PDF]

open access: yes, 2014
Asymptotic random dynamics of weak solutions for a damped stochastic wave equation with the nonlinearity of arbitrarily large exponent and the additive noise on $\mathbb{R}^n$ is investigated.

Random sampling vs. exact enumeration of attractors in random Boolean networks [PDF]

open access: yes, 2009
We clarify the effect different sampling methods and weighting schemes have on the statistics of attractors in ensembles of random Boolean networks (RBNs).

The random case of Conley's theorem

open access: yes, 2005
The well-known Conley's theorem states that the complement of chain recurrent set equals the union of all connecting orbits of the flow $\phi$ on the compact metric space $X$, i.e.

Invariant measures and random attractors of stochastic delay differential equations in Hilbert space

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2022
This paper is devoted to a general stochastic delay differential equation with infinite-dimensional diffusions in a Hilbert space. We not only investigate the existence of invariant measures with either Wiener process or Lévy jump process, but also ...

Chaotic itinerancy and power-law residence time distribution in stochastic dynamical system

open access: yes, 2005
To study a chaotic itinerant motion among varieties of ordered states, we propose a stochastic model based on the mechanism of chaotic itinerancy. The model consists of a random walk on a half-line, and a Markov chain with a transition probability matrix.

Asymptotic behaviour of random tridiagonal Markov chains in biological applications

open access: yes, 2012
Discrete-time discrete-state random Markov chains with a tridiagonal generator are shown to have a random attractor consisting of singleton subsets, essentially a random path, in the simplex of probability vectors.

The effect of Hebbian plasticity on the attractors of a dynamical system [PDF]

open access: yes, 2008
Poster presentation A central problem in neuroscience is to bridge local synaptic plasticity and the global behavior of a system. It has been shown that Hebbian learning of connections in a feedforward network performs PCA on its inputs [1]. In recurrent
