度量空间的g-函数新刻划

New characterizations of metrizerble space in terms of g-fuctions

g 函数是研究度量空间与广义度量空间的有力工具之一 近年来 ,人们给出了度量空间关于g 函数的许多不同的刻划 ,此文借助于g 函数给出了度量空间的一些新刻划 。

Some new characterizations of metrizable space in terms of g functions were proved,these results are generalizations of some theorems obtained by GAO Zi ming and others.
