| Resumo | |
In this paper we study the hyperspace of nontrivial convergent sequences of ordinal spaces. We prove that w(omega) characterizes all hyperspaces S-c([0, alpha)) for omega < alpha < 2 omega. Also we improve a result from [4] by showing that S-c([0, alpha)) has the Baire property for every alpha > omega . Finally we show that the closure of S-c([0,alpha)) in K([0,alpha)) is a zero dimensional compactification of S-c([0,alpha)) which differs from its Stone-& Ccaron;ech compactification.
