Random Expansive Measures

Abstract

The notions of expansive measures; expansive, positively expansive, measureexpansive, countably expansive and continuum-wise homeomorphisms are well known for the deterministic case. In this paper, we extend these notions to the random context and prove that some of them are particular cases of others and some of them are equivalents. Also, we show that every ergodic probability with positive entropy is positively random expansive.
