研究了可数离散交换群作用的测度敏感性,并研究了相关性质.并且对一个极小系统,我们给出了测度”一敏感但不是(n+1)一敏感的系统的结构的一个刻画.
We introduce the notion of measurable sensitivity for countable discreter abelian group action and study some of its properties. For minimal system, we give a characterization of a minimal system which is measurable n- sensitive but not (n+1) -sensitive.
