摘要:
证明了对于可数无限离散双序顺从群G-系统,正熵蕴含着平均Li-Yorke混沌.给出了整数格群和整数幂幺上三角形矩阵群的例子。
英文摘要:
It is proved that positive entropy implies mean Li-Yorke chaos for a G-system, where G is a countable infinite discrete bi-orderable amenable group. Examples are given for the cases of integer lattice groups and groups of integer unipotent upper triangular matrices.
