The sizes of relatively compact $T_{1}$ -spaces

Winfried Just (1996)

Commentationes Mathematicae Universitatis Carolinae

Similarity:

The relativization of Gryzlov’s theorem about the size of compact $T_{1}$ -spaces with countable pseudocharacter is false.

Local cardinal functions of H-closed spaces

Angelo Bella, Jack R. Porter (1996)

Commentationes Mathematicae Universitatis Carolinae

Similarity:

The cardinal functions of pseudocharacter, closed pseudocharacter, and character are used to examine H-closed spaces and to contrast the differences between H-closed and minimal Hausdorff spaces. An H-closed space $X$ is produced with the properties that $| X | > 2^{2^{ψ (X)}}$ and $\bar{ψ} (X) > 2^{ψ (X)}$ .
