On pseudo-sequence-covering -images of locally separable metric spaces.
-mappings in -Ponomarev-systems
We use the -Ponomarev-system , where is a locally separable metric space, to give a consistent method to construct a -mapping (compact mapping) with covering-properties from a locally separable metric space onto a space . As applications of these results, we systematically get characterizations of certain -images (compact images) of locally separable metric spaces.
