内容简介

本卷收录了吴文俊的A Theory of Imbedding, Immersion, and Isotopy of
Polytopes in a Euclidean Space 一书. 一个空间嵌入另一空间(例如欧氏空
间)是否可能以及这些嵌入所依据的同痕的分类问题, 已成为拓扑学中重
要的中心问题之一, 也是许多拓扑学家从各种不同角度用各种不同方法
研究的对象之一. 本书是作者从1954 年以来在这方面研究工作的一个总
结报告, 它的方法在于研究空间的去核p 重积, 即将p 重积除去对角以后
所余的空间, 这一概念可追溯到Van Kampen 早在1932 年的一篇重要论文.
其次再应用P. A. Smith 有关周期变换的理论以获得若干作为Smith 特殊群
中上类的不变量, 它们之为0 是嵌入的必要条件而在某些极端情形又同时
为充分条件. 关于嵌入的许多已知结果以及一些新的结果, 虽有着种种不
同的来源, 都可用这一统一的方法得出. 浸入与同痕也可用同样办法处理
并得出相应的类似结果.
