We characterize measure-theoretic sequence entropy pairs of continuous actions of abelian groups using mean sensitivity. This addresses an open question of Li and Yu [On mean sensitive tuples. J. Differential Equations297 (2021), 175–200]. As a consequence of our results, we provide a simpler characterization of Kerr and Li’s independence sequence entropy pairs ( $\mu $ -IN-pairs) when the measure is ergodic and the group is abelian.

测度理论序列熵对和平均灵敏度

我们使用平均灵敏度来表征阿贝尔群连续行为的测度理论序列熵对。这解决了 Li 和 Yu 的一个悬而未决的问题[关于平均敏感元组。J. 微分方程297(2021),175-200]。根据我们的结果,我们提供了 Kerr 和 Li 的独立序列熵对的更简单的表征( $\亩$ -IN-pairs) 当测度是遍历且群是交换群时。
