Characterizations of $N$ -compactness and realcompactness via ultrafilters in the absence of the axiom of choice

AliReza Olfati, Eliza Wajch

This article concerns the Herrlich-Chew theorem stating that a Hausdorff zero-dimensional space is $N$ -compact if and only if every clopen ultrafilter with the countable i…

Quasiorders for a characterization of iso-dense spaces

Tom Richmond, Eliza Wajch

A (generalized) topological space is called an iso-dense space if the set of all its isolated points is dense in the space. The main aim of the article is to show in $ZF$ …
