In this paper, we give the mapping theorems on $ℵ$ -spaces and $g$ -metrizable spaces by means of some sequence-covering mappings, mssc-mappings and $π$ -mappings.

Weak-open compact images of metric spaces

The main results of this paper are that (1) a space $X$ is $g$ -developable if and only if it is a weak-open $π$ image of a metric space, one consequence of the result being the correction of an error in the paper of Z. Li and S. Lin; (2) characterizations of weak-open compact images of metric spaces, which is another answer to a question in in the paper of Y. Ikeda, C. liu and Y. Tanaka.

On weak-open $π$ -images of metric spaces

Zhaowen Li (2006)

Czechoslovak Mathematical Journal

Similarity:

In this paper, we give some characterizations of metric spaces under weak-open $π$ -mappings, which prove that a space is $g$ -developable (or Cauchy) if and only if it is a weak-open $π$ -image of a metric space.
