内容简介

This volume covers approximately the amount of point-set topology that a student who does not intend to specialize in the field should nevertheless know.This is not a whole lot， and in condensed form would occupy perhaps only a small booklet. Our aim， however， was not economy of words， but a lively presentation of the ideas involved， an appeal to intuition in both the immediate and the higher meanings.

不错 上课用的

之前上分析学老师从集合角度出发引出的连续过渡到需要拓扑空间来弥补的地方没听懂，这本书开头就详述了集合和拓扑点的关系，非常到位，观点很细腻，书不厚，就一百五六十页，可以很快读完，但是回味很久。这本书不是普通意义上的教材，作者观点很高但是起点很低，讲解了拓扑学的精到之处，顺手拈来在其他领域的应用，并且恰到好处，尤其是对克莱因瓶的解释很棒，适合有了一定基础又需要整体把握的童鞋们和自学者，推荐。

UTM这个系列都很经典。

这本书不是传统意义上的拓扑教科书，但对于初学者深入了解一般拓扑学具有巨大价值。笔者大约在二十年前曾非常仔细地读过这本书（至少3遍），是我为数不多的从头至尾全部阅读过的书之一。笔者强烈推荐给现在正在学习数学的读者。

用比较综观的观点来讲拓扑，有新意，不错！
