The main purpose of this paper is to establish general conditions under which $T_{2}$ -spaces are compact-covering images of metric spaces by using the concept of $c f p$ -covers. We generalize a series of results on compact-covering open images and sequence-covering quotient images of metric spaces, and correct some mapping characterizations of $g$ -metrizable spaces by compact-covering $σ$ -maps and $m s s c$ -maps.

The class of $ℵ$ -spaces is invariant of closed mappings with Lindelöf fibres

Similarity:

Some relationships between $1$ -sequence-covering maps and weak-open maps or sequence-covering $s$ -maps are discussed. These results are used to generalize a result from Lin S., Yan P., , Topology Appl. (2001), 301–314.
