Abstract

It is proved that no non-meager subspace of the space [ω]ω[ω]^ω equipped with the Ellentuck topology does admit a Kuratowski partition, that is such a subset cannot be covered by a family F\mathfrak{F} of disjoint relatively meager sets such that ⋃F′\bigcup\mathfrak{F}' has the Baire property (relatively) for every subfamily F′⊆F\mathfrak{F}'\subseteq\mathfrak{F}. It is also shown that the existence of Kuratowski partitions is not a metric problem. Some remarks concerning continuous restrictions of functions with domain in the Ellentuck space are made.
