✦ Synopsis


In this paper, we give a characterization of countable compacta which admit expansive homeomorphisms. The main result is the following:

Theorem. Let X be a countable compactum and d(X) = Ξ±, where d(X) is the derived degree of X. Then X admits an expansive homeomorphism if and only if Ξ± is not a limit ordinal number.
