It is proved that the product of two pseudo radial compact spaces is pseudo radial provided that one of them is monolithic.

On subspaces of pseudo-radial spaces

Jin Yuan Zhou (1993)

Commentationes Mathematicae Universitatis Carolinae

Similarity:

It is proved that, under the Martin’s Axiom, every $T_{1}$ -space with countable tightness is a subspace of some pseudo-radial space. We also give several characterizations of subspaces of pseudo-radial spaces and conclude that being a subspace of a pseudo-radial space is a local property.
