细胞自动机的重标度熵

Rescaled entropy of cellular automata

David Burguet

摘要:

对于d $\ge$ 1的d维元胞自动机,我们引入了一个重新标度的熵,它通过推广以前的方法[1,9]来估计小尺度下熵的增长率。我们还定义了一个李雅普诺夫指数的概念,并证明了一个Ruelle不等式,如[16,15]中对d = 1所建立的那样。最后,我们将一维置换细胞自动机的熵公式推广到高维的重标熵。最后一个结果扩展了Shinoda和Tsukamoto最近的工作[17],涉及二维符号动力学的度量平均维数。

英文摘要:

For a d-dimensional cellular automaton with d $\ge$ 1 we introduce a rescaled entropy which estimates the growth rate of the entropy at small scales by generalizing previous approaches [1, 9]. We also define a notion of Lyapunov exponent and proves a Ruelle inequality as already established for d = 1 in [16, 15]. Finally we generalize the entropy formula for 1-dimensional permutative cellular automata [18] to the rescaled entropy in higher dimensions. This last result extends recent works [17] of Shinoda and Tsukamoto dealing with the metric mean dimensions of two-dimensional symbolic dynamics.
