得到了Vietoris-like超空间拓扑的一般选择定理,从而从一个共同的观点改进了几个已知的“拓扑”-生成超空间拓扑和“度量”-生成超空间拓扑的选择定理.应用连续选择的超空间的可度量空间类的特征。1991年数学科目分类:小学54 B20、54 C65;中学54 E45、54 D 65、54 E40、54 C10、54 G12。
A general selection theorem for a Vietoris‐like hyperspace topology is obtained and, as a result, several known selection theorems for both ‘topology’‐ and ‘metric’‐generated hyperspace topologies are improved from a common point of view. Applications are presented in characterizing classes of metrizable spaces by continuous selections for their hyperspaces. 1991 Mathematics Subject Classification: primary 54B20, 54C65; secondary 54E45, 54D65, 54E40, 54C10, 54G12.
