Diagonalizations of dense families
Maddalena Bonanzinga, Filippo Cammaroto, Bruno Antonio Pansera +1
We develop a unified framework for the study of properties involving diagonalizations of dense families in topological spaces. We provide complete classification of these propertie…
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…
