对“强关联系统的大偏差理论”一文的评论

Comment on "Towards a large deviation theory for strongly correlated systems"

Hugo Touchette

摘要:

我评论最近的一篇论文鲁伊斯和Tsallis [物理。A 376,2451(2012)]声称已经发现了强相关随机变量的大偏差原理的“$q$ -指数”推广。我表明,他们发现的基本缩放结果可以用一个简单的例子,涉及独立的随机变量,并没有特别相关的$q$指数函数。事实上,相同的标度结果可以用指数的任何其他幂律变形来获得。因此,他们的结果并不最终支持他们声称的大偏差原理的$q$ -指数推广。

英文摘要:

I comment on a recent paper by Ruiz and Tsallis [Phys. Lett. A 376, 2451 (2012)] claiming to have found a '$q$-exponential' generalization of the large deviation principle for strongly correlated random variables. I show that the basic scaling results that they find numerically can be reproduced with a simple example involving independent random variables, and are not specifically related to the $q$-exponential function. In fact, identical scaling results can be obtained with any other power-law deformations of the exponential. Thus their results do not conclusively support their claim of a $q$-exponential generalization of the large deviation principle.
