For a T0 space X, let K(X) be the poset of all non-empty compact saturated sets.of X with the reverse inclusion order. The space X is said to have property Q if.for any K1, K2 ∈ K(X), K1 K2 in K(X) iff K2 ⊆ int K1. In this paper, we give.several connections among the well-filteredness of X, the sobriety of X, the local.compactness of X, the core compactness of X, the property Q of X, the coincidence.of the upper Vietoris topology and Scott topology on K(X), and the continuity of.x → ↑x : X −→ ΣK(X) (where ΣK(X) is the Scott space of K(X)). It is shown that.for a well-filtered space X for which its Smyth power space PS(X) is first-countable,.the following three properties are equivalent: the local compactness of X, the core.compactness of X and the continuity of K(X). It is also proved that for a firstcountable T0 space X in which the set of minimal elements of K is countable for any.compact saturated subset K of X, the Smyth power space PS(X) is first-countable..For the Alexandroff double circle Y , which is Hausdorff and first-countable, we show.that its Smyth power space PS(Y ) is not first-countable.
