关于超空间局部有限拓扑的局部覆盖性质

Local Covering Properties of Hyperspace 2x with Locally Finite Topology

本文赋予超空间 2 X 局部有限拓扑 ,并讨论此空间的一些局部覆盖性质 .证明 2 X 中的某些覆盖性质等价于局部性质 .

In this paper,we discuss some local covering properties of 2 X with locally finite topology,and prove that some covering properties are equivalent to local properties in 2 X .
