Weak-bases and $D$ -spaces

Dennis K. Burke (2007)

Commentationes Mathematicae Universitatis Carolinae

Similarity:

It is shown that certain weak-base structures on a topological space give a $D$ -space. This solves the question by A.V. Arhangel’skii of when quotient images of metric spaces are $D$ -spaces. A related result about symmetrizable spaces also answers a question of Arhangel’skii. Hence, quotient mappings, with compact fibers, from metric spaces have a $D$ -space image. What about quotient $s$ -mappings? Arhangel’skii and Buzyakova have shown that spaces with a point-countable base...

A generalization of boundedly compact metric spaces

Gerald Beer, Anna Di Concilio (1991)

Commentationes Mathematicae Universitatis Carolinae

Similarity:

A metric space $〈 X, d 〉$ is called a $UC$ space provided each continuous function on $X$ into a metric target space is uniformly continuous. We introduce a class of metric spaces that play, relative to the boundedly compact metric spaces, the same role that $UC$ spaces play relative to the compact metric spaces.
