$n$ -H-closed spaces

Fortunata Aurora Basile, Maddalena Bonanzinga, Nathan Carlson +1

In this paper we extend the theory of H-closed extensions of Hausdorff spaces to a class of non-Hausdorff spaces, defined in \cite{B}, called $n$ -Hausdorff spaces. The notion of H-…

On cardinality bounds for $θ^{n}$ -Urysohn spaces

Fortunata Aurora Basile, Nathan Carlson, Jack Porter

We introduce the class of $θ^{n}$ -Urysohn spaces and the $n$ - $θ$ -closure operator. $θ^{n}$ -Urysohn spaces generalize the notion of a Urysohn space. We estabilish bounds on the cardin…
