Mapping theorems on quasi - nagata spaces
空间的映射定理
In this paper , we give a new characterization of metrizable spaces in terms of g - functions to answer nagata ' s question and equivalent characterizations of - spaces , spaces with - cp cs - network in terms of g - functions . we give weak g - functions as the generalizations of g - functions and cwbc - map , and we characterize some metrizable spaces in terms of weak g - functions
本文利用g -函数给出了度量空间的一个新刻划，回答了nagata的问题，并利用g -函数给出了-空间、具有- cpcs -网的空间的等价刻划，我们还将g -函数与cwbc -映射统一推广为弱g -函数，并利用弱g -函数刻划了一些度量空间。
