摘要: 该文证明具有弱specification性质的系统在其测度中心的限制系统也具有弱specification性质,并且其逆不真.作为推论得到在未有满射的假设下,弱specification性质蕴含渐近平均跟踪性质.最后证明具有弱specification性质的满射系统是一致分布混沌的.

关键词: 测度中心, 弱specification, 渐近平均跟踪性质, 分布混沌

Abstract: This note proves that if a dynamical system has the weak specification property, then so does the dynamical system restricted on its measure center, and the converse does not hold. As a corollary, it is obtained that the weak specification property implies asymptotic average shadowing (no assumption that the map is onto). Finally, it is proved that every surjective system having the weak specification property exhibits uniformly distributional chaos.

Key words: Measure center, Weak-specification, Asymptotic average shadowing, Distributional chaos
