Countable compactness in powers of topological groups and Ramsey theoretic variations of compactness
Vinicius de Oliveira Rodrigues, Paul Jan Szeptycki, Artur Hideyuki Tomita
Countable compactness need not be preserved by finite products. Motivated by compactness notions for maps indexed by finite subsets of , we introduce cascade countable compactne…
Semi-proximal spaces and normality
Khulod Almontashery, Paul Szeptycki
We consider the relationship between normality and semi-proximality. We give a consistent example of a first countable locally compact Dowker space that is not semi-proximal, and t…
Special sets of reals and weak forms of normality on Isbell-Mrówka spaces
Vinicius Rodrigues, Victor dos Santos Ronchim, Paul Szeptycki
We recall some classical results relating normality and some natural weakenings of normality in -spaces over almost disjoint families of branches in the Cantor tree to special s…
On a topological Ramsey Theorem
Wiesław Kubiś, Paul Szeptycki
We introduce natural strengthenings of sequential compactness called the -Ramsey property for each natural number . We prove that metrizable compact spaces are -Rams…
Weak normality properties in -spaces
Sergio A, Garcia-Balan, Paul J. Szeptycki
Almost disjoint families of true cardinality are used to produce an example of a mildly-normal not partly-normal -space and a quasi-normal not almost-normal -s…
Selectivity properties of spaces
William Chen-Mertens, Paul J. Szeptycki
This paper addresses several questions of Feng, Gruenhage, and Shen which arose from Michael's theory of continuous selections from countable spaces. We construct an example of a s…
