Observations on spaces with zeroset or regular -diagonals
Raushan Z. Buzyakova (2005)
Commentationes Mathematicae Universitatis Carolinae
We show that if has countable extent and has a zeroset diagonal then is submetrizable. We also make a couple of observations regarding spaces with a regular -diagonal.

On character and chain conditions in images of products
Murray Bell (1998)
Fundamenta Mathematicae
A scadic space is a Hausdorff continuous image of a product of compact scattered spaces. We complete a theorem begun by G. Chertanov that will establish that for each scadic space X, χ(X) = w(X). A ξ-adic space is a Hausdorff continuous image of a product of compact ordinal spaces. We introduce an either-or chain condition called Property which we show is satisfied by all ξ-adic spaces. Whereas Property is productive, we show that a weaker (but more natural) Property is not productive. Polyadic...

On compact spaces carrying Radon measures of uncountable Maharam type
David Fremlin (1997)
Fundamenta Mathematicae
If Martin’s Axiom is true and the continuum hypothesis is false, and X is a compact Radon measure space with a non-separable space, then there is a continuous surjection from X onto .

On D-dimension of metrizable spaces
Wojciech Olszewski (1991)
Fundamenta Mathematicae
For every cardinal τ and every ordinal α, we construct a metrizable space and a strongly countable-dimensional compact space of weight τ such that , and each metrizable space X of weight τ such that D(X) ≤ α is homeomorphic to a subspace of and to a subspace of .
