<i>F</i><sup>′</sup>-spaces and their product with<i>P</i>-spaces
The F'-spaces studied here, introduced by Leonard Gillman and Melvin Henriksen, are by definition completely regular Hausdorff spaces in which disjoint cozero-sets have disjoint closures.The principal result of this paper gives a sufficient condition that a product space be an F 1 -space and shows that the condition is, in …
