On the average-shadowing property. (English) Zbl 1022.37017
Summary: It is proved that a homeomorphism on a compact metric space with the average-shadowing property has only one chain component which is the whole space. In particular, every point is chain recurrent. Using this result a short proof for a recent theorem of Sakai is given.
