The Asymptotic Average Shadowing Property and Its Applications

Let （X, d） be a bounded metric space and f ： X → X be a uniformly continuous surjection. For a given dynamical system （X, f） which may not be compact, we investigate the relation between the asymptotic average shadowing property（AASP）, transitivity and mixing. If f has the AASP, then the following statements hold： （1） f n is chain transitive for every positive integer n; （2） If X is compact and f is an expansive homeomorphism, then f is topologically weakly mixing; （3） If f is equicontinuous, then f is topologically weakly mixing; （4） If X is compact and f is equicontinuous, then f ×f is a minimal homeomorphism. We also show that the one-sided shift map has the AASP and the identity map 1 X does not have the AASP. Furthermore, as its applications, some examples are given.
