The Kirch space is topologically rigid
Taras Banakh, Yaryna Stelmakh, Sławomir Turek
The (resp. the ) is the set of positive integers endowed with the topology generated by the base consisting of arithmetic progressions $…
Vietoris hyperspaces of scattered Priestley spaces
T. Banakh, R. Bonnet, W. Kubiś
We study Vietoris hyperspaces of closed and closed final sets of Priestley spaces. We are particularly interested in Skula topologies. A topological space is \emph{Skula} if its to…
Null sets and combinatorial covering properties
Piotr Szewczak, Tomasz Weiss
A subset of the Cantor cube is null-additive if its algebraic sum with any null set is null. We construct a set of cardinality continuum such that: all continuous images of the set…
The Golomb space is topologically rigid
Taras Banakh, Dario Spirito, Sławomir Turek
The is the set of positive integers endowed with the topology generated by the base consisting of arithmetic progressions $\{a+bn:n\g…
Supercompact minus compact is super
Taras Banakh, Zdzisław Kosztołowicz, Sławomir Turek
According to a folklore characterization of supercompact spaces, a compact Hausdorff space is supercompact if and only if it has a binary closed -network. This characterization…
Hausdorff Tight Groupoids Generalised
Tristan Bice, Charles Starling
We extend Exel's ample tight groupoid construction to general locally compact étale groupoids in the Hausdorff case. Moreover, we show how inverse semigroups are represented in thi…
