一类混沌区域的等熵扰动

Isentropic perturbations of a chaotic domain

I. I. Shevchenko

摘要:

研究了标准映射的混沌动力学的三个主要性质,即主连通混沌区域的测度μ、主连通混沌区域内运动的最大李雅普诺夫指数L和动力学熵h = μL随随机性参数K的变化.特别考虑了由于稳定岛的出现和解体而引起的域的扰动,K的变化很小。通过大量的数值试验,证明了这些扰动是等熵的(至少是近似的)。换句话说,动力学熵没有波动,而μ和L的局部跳跃是显著的。

英文摘要:

Three major properties of the chaotic dynamics of the standard map, namely, the measure μof the main connected chaotic domain, the maximum Lyapunov exponent L of the motion in this domain, and the dynamical entropy h = μL are studied as functions of the stochasticity parameter K. The perturbations of the domain due to emergence and disintegration of islands of stability, upon small variations of K, are considered in particular. By means of extensive numerical experiments, it is shown that these perturbations are isentropic (at least approximately). In other words, the dynamical entropy does not fluctuate, while local jumps in μand L are significant.
