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.

就笔者所知，原书作者Klaus Jaenich写过一本著名的微分拓扑方面的教材（原文为德文，后由剑桥大学出版社出版了英文版），还写了好几本风格类似的教科书，包括线性代数、复分析、向量分析，但好像都没有英文版的。
