重叠字母符号动力学的熵

Entropy for symbolic dynamics with overlapping alphabets

Fabio Drucker, David Richeson, Jim Wiseman

摘要:

我们考虑移位空间中的字母表的元素可以重叠非传递。我们定义了这样的空间熵的概念,给出了几种计算它的下界的技术,并表明它等于(标准)全移位熵的极限。当具有重叠的移位空间作为具有有限个重叠邻域集的离散动力系统的模型出现时,熵给出了动力系统的拓扑熵的下界。

英文摘要:

We consider shift spaces in which elements of the alphabet may overlap nontransitively. We define a notion of entropy for such spaces, give several techniques for computing lower bounds for it, and show that it is equal to a limit of entropies of (standard) full shifts. When a shift space with overlaps arises as a model for a discrete dynamical system with a finite set of overlapping neighborhoods, the entropy gives a lower bound for the topological entropy of the dynamical system.
