Topological spaces containing compact perfect sets and Prohorov spaces. (English) Zbl 0574.54041
Generalizing the known facts for Borel and Suslin subsets of complete metric spaces, the author proves that if X is either Čech-analytic or first countable Prokhorov-analytic, then X is $$\sigma$$-scattered or contains a compact perfect set. The assertion implies e.g. that every first-countable Prokhorov space is a Baire space, that the Sorgenfrey line is not Prokhorov (neither Prokhorov-analytic). First-countable scattered and $$\sigma$$-scattered spaces are then characterized by means of the Prokhorov property.
