We present a construction from ♢* of a first countable, regular, countably metacompact space with a closed discrete subspace that is not a . In addition some nonperfect spaces with σ-disjoint bases are constructed.

We give an example of a compact space X whose iterated continuous function spaces , are Lindelöf, but X is not a Corson compactum. This solves a problem of Gul’ko (Problem 1052 in [11]). We also provide a theorem concerning the Lindelöf property in the function spaces on compact scattered spaces with the th derived set empty, improving some earlier results of Pol [12] in this direction.
