Infima and cardinal characteristics of critical ideals for countable compact spaces

Malgorzata Kowalczuk

For each countable ordinal $α \geq 2$ , the ideals $conv_{α}$ were introduced in ``Critical ideals for countable compact spaces'' (to appear in Fund. Math., see also arXiv:2503…

Critical partition regular functions for compact spaces

Rafał Filipów, Małgorzata Kowalczuk, Hubert Książek +2

We study ideal-based refinements of sequential compactness arising from the class FinBW(I), consisting of topological spaces in which every sequence admits a convergent subsequence…

Critical ideals for compact spaces

Rafał Filipów, Małgorzata Kowalczuk, Adam Kwela

For each countable ordinal $α$ , we introduce an ideal $co n v_{α}$ and use it to characterize the class of all compact countable spaces which are homeomorphic to the space $ω^α\cdot n+…
