摘要
利用g-函数研究广义度量空间和度量化,统一了近年来许多有趣的工作.本文回答了[2]中提出的一个问题.所讨论的拓扑空间是正则的.
In [2] the charactcrizations of metrizable spaces by g-function were discussed, and J. Nagata raised the following question: Find a condition which is weaker than condition (3) and combine it with condition (1), and this characterizes the metrizability of a space. In this paper the author discusses the question.
