In this paper internal characterization on certain quotient images of locally separable metric spaces are discussed. We obtain some descriptions of quotients-images, pseudo-opens-images, quotient compact images and closed images of locally separable metric spaces, and establish some relations between these and certain quotient images of metric spaces by the local separability of suitable subspaces.

Quotient compact images of metric spaces, and related matters
Abstract As a generalization of developments of (developable) spaces, we introduce the notion of σ -strong networks of spaces, and related notions. We give new characterizations for around quotientExpand

TLDR
The characterizations of metric spaces under compact-covering and π-s-maps are established by means of cfp-covers (resp., sfp- covers, cs-co covers) and σ-strong networks. Expand
