“Isotopy”的概念、定义、习题解题方法及翻译-数学辞典

单词	Isotopy
释义	isotopy Let $M$ and $N$ be manifolds and $I=[0,1]$ the closed unit interval. A smooth map $h\\colon M\\times I\\to N$ is called an isotopy if the restriction map $h_{t}:=h(-,t):M\\to N$ is an embedding for all $t\\in I$ . In particular, a diffeotopy is an isotopy. Remark. Given an isotopy $h\\colon M\\times I\\to N$ , there exists a diffeotopy $g\\colon N\\times I\\to N$ such that $h_{t}=g_{t}\\circ h_{0}$ .
