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.

有关拓扑学的一些内容早在十八世纪就出现了。那时候发现一些孤立的问题，后来在拓扑学的形成中占着重要的地位。譬如哥尼斯堡七桥问题、多面体的欧拉定理、四色问题等都是拓扑学发展史的重要问题。 七桥问题 主条目：七桥问题 哥尼斯堡七桥问题 哥尼斯堡是东普鲁士的首都，普莱格尔河横贯其中。十八世纪在这条河上建有七座桥，将河中间的两个岛和河岸联结起来。一天有人提出：能不能每座桥都只走一遍，最后又回到原来的位置。这个看起来很简单又很有趣的问题吸引了大家，很多人在尝试各种各样的走法，但谁也没有做到。 1736年，有人带着这个问题找到了当时的大数学家欧拉，欧拉经过一番思考，很快就用一种独特的方法给出了解答。这是拓扑学的“先声”。[1] 欧拉定理 拓扑学 在拓扑学的发展历史中，还有一个著名而且重要的关于多面体的定理也和欧拉有关。
