随机生成amenable groups的符号动力学中的平均维数论

Mean dimension theory in symbolic dynamics for finitely generated amenable groups

Yunping Wang, Ercai Chen, Xiaoyao Zhou

摘要:

本文主要阐明多项式增长群作用的拓扑熵与平均维数论之间的密切关系。证明了低秩子群的子移位的度量平均维数和平均豪斯多夫维数等于其拓扑熵乘以子群的增长率.同时,我们还证明了上述结果对于子移位关于低秩子群和测度熵的率失真维数也成立。此外,还列举了一些相关的例子。

英文摘要:

In this paper, we mainly elucidate a close relationship between the topological entropy and mean dimension theory for actions of polynomial growth groups. We show that metric mean dimension and mean Hausdorff dimension of subshifts with respect to the lower rank subgroup are equal to its topological entropy multiplied by the growth rate of the subgroup. Meanwhile, we also prove the above result holds for the rate distortion dimension of subshifts with respect to the lower rank subgroup and measure entropy. Furthermore, some relevant examples are indicated.
