On the cardinality of Hausdorff spaces
Filippo Cammaroto, Andrei Catalioto, Jack Porter
A common generalization for two of the main streams of cardinality inequalities is developed; each stream derives from the famous inequality established by A.V. Arhangel'ski\uı in…
Absolutes of Hausdorff spaces and cardinal invariants $F_{\te}$ and $t_{\te}$}
Filippo Cammaroto, Andrei Catalioto, Jack Porter
This article extends the recent study of the cardinal functions and for H-closed Urysohn spaces and the research of I. Bandlov and V.I. Ponomarev on tightness type of a…
Cardinal functions and for H-closed spaces
Filippo Cammaroto, Andrei Catalioto, Jack Porter
In this article, starting with results from a paper by Cammaroto and Kočinac in 1993, we prove that for every H-cl…
On the cardinality of the -closed hull of sets II
Filippo Cammaroto, Andrei Catalioto, Bruno Antonio Pansera +1
The research in this paper is a continuation of the investigation of the cardinality of the -closed hull of subsets of spaces. This research obtains new upper bounds of the card…
On the cardinality of the -closed hull of sets
Filippo Cammaroto, Andrei Catalioto, Bruno Antonio Pansera +1
The θ-closed hull of a set A in a topological space is the smallest set C containing A such that, whenever all neighborhoods of a point intersect C, this point is in C. We…
