An extension of $F$ -spaces and its applications

A. R. Aliabad, A. Taherifar

A completely regular Hausdorff space $X$ is called a $W C F$ -space if every pair of disjoint cozero-sets in $X$ can be separated by two disjoint $Z^{\circ}$ -sets. The class of $W C F$ -…

On $z^{\circ}$ -ideals and annihilator ideals

A. Taherifar

For $a \in R$ , let $P_{a}$ denote the intersection of all minimal prime ideals of $R$ containing $a$ . An ideal $I$ of a ring $R$ is called a $z^{\circ}$ -ideal if $P_{a} \subseteq I$ for…
