关于k-映射

ON k-MAPPINGS

本文给出度量空间 k-映象的一些新的特征 .证明了 k-映射保持一些具有某种特定性质的点可数覆盖的空间 .

In this paper,we give a internal characterization of k mapping images of metric spaces and obtain a metrizable theorem.It is shown that spaces with a point countable sk network (k network,p sk network or p k network) are preserved by k mappings.
