L-Ponomarev system and images of locally separable metric spaces

We introduce the notion of an L-Ponomarev system (f,M,X, P*n), and give characterizations of certain msss-images (resp., mssc-images) of locally separable metric spaces. As an application, we get a new characterization of quotient msss-images (mssc-images) of locally separable metric spaces, which i...

Summary:We introduce the notion of an L-Ponomarev system (f,M,X, P*n), and give characterizations of certain msss-images (resp., mssc-images) of locally separable metric spaces. As an application, we get a new characterization of quotient msss-images (mssc-images) of locally separable metric spaces, which is helpful in solving Velichko?s question (1987). nema
