关于具有σ-局部有限cs-网的空间

On spaces with σ-locally finite cs-network

利用σ-映射与m ssc-映射建立了具有σ-局部有限cs-网、σ-局部有限cs*-网的空间以及X-空间与度量空间确定映象之间的联系,得到了具有σ-局部有限cs-网空间的一些等价条件.

The relation between the σ-images of metrizable spaces and spaces with σ-locally finite cs-network,or spaces with σ-locally finite cs＊-network,and X-spaces are established by use of σ-mapping and mssc-mapping.Some equivalent conditions of spaces with σ-locally finite cs-network are obtained.
