摘要翻译:
本文回顾了关于特殊相关(或q独立)变量和的中心极限定理的最新推广,重点是q大于或等于1。具体地说,这种关联将熵Sq最大化时出现的概率密度函数q-高斯函数变成概率空间中的吸引子。此外,我们还讨论了a-稳定Levy分布的一个q-推广,它对这类特殊的关联也是稳定的。在此背景下,我们证明了一个三重熵指数的出现,它与吸引子的形式、关联和标度率有关,类似于将反常系统中表征初始条件敏感性、稳态和弛豫到稳态的熵指数联系起来的q-三重熵指数。

英文摘要:
In this article we review recent generalisations of the central limit theorem for the sum of specially correlated (or q-independent) variables, focusing on q greater or equal than 1. Specifically, this kind of correlation turns the probability density function known as q-Gaussian, which emerges upon maximisation of the entropy Sq, into an attractor in probability space. Moreover, we also discuss a q-generalisation of a-stable Levy distributions which can as well be stable for this special kind of correlation.Within this context, we verify the emergence of a triplet of entropic indices which relate the form of the attractor, the correlation, and the scaling rate, similar to the q-triplet that connects the entropic indices characterising the sensitivity to initial conditions, the stationary state, and relaxation to the stationary state in anomalous systems.
