噪声可以减少混沌动力学中的无序

Noise Can Reduce Disorder in Chaotic Dynamics

Denis S. Goldobin

摘要:

我们唤起的想法表示的混沌吸引子的不稳定周期轨道的集合,并揭示了一种新的噪声诱导的有序现象。对于形成奇异吸引子的长不稳定周期轨道,权重(或自然测度)在集合上通常是高度不均匀的,从而减少或增强这些轨道对系统动力学的贡献。我们分析和数值计算表明,弱噪声,以减少这种不均匀性,除了明显的扰动影响,使混沌动力学的正则化的影响。这种普遍的影响根植于确定性混沌的本质。

英文摘要:

We evoke the idea of representation of the chaotic attractor by the set of unstable periodic orbits and disclose a novel noise-induced ordering phenomenon. For long unstable periodic orbits forming the strange attractor the weights (or natural measure) is generally highly inhomogeneous over the set, either diminishing or enhancing the contribution of these orbits into system dynamics. We show analytically and numerically a weak noise to reduce this inhomogeneity and, additionally to obvious perturbing impact, make a regularizing influence on the chaotic dynamics. This universal effect is rooted into the nature of deterministic chaos.
