Topological Spaces with the Freese–Nation Property

open access: yesAnnales Mathematicae Silesianae, 2019
We give a proposal of generalization of the Freese–Nation property for topological spaces. We introduce a few properties related to Freese–Nation property: FNS, FN, FNS*, FNI. This article presents some relationship between these concepts.

Ideals without ccc

open access: yesJournal of Symbolic Logic, 1998
AbstractLet I be an ideal of subsets of a Polish space X, containing all singletons and possessing a Borel basis. Assuming that I does not satisfy ccc, we consider the following conditions (B), (M) and (D). Condition (B) states that there is a disjoint family F ⊆ P(X) of size ϲ, consisting of Borel sets which are not in I.
