作者:Hirsch,MW|翻译后摘要:假设n,k,m,q是正整数。设M^n表示光滑可微n-流形,R^k表示欧氏k-空间。(a)若M^n是开的,则它光滑地嵌入R^k,k=2n-1(B)若M^n是开的且可并行的,则它浸入R^n(c)设M^n是闭的且(m-1)-连通的,1 l 2 m-n l n+1。如果(n-m)-骨架的邻域浸入R^q,ag 2n-2 m,则M^n的点的补光滑地嵌入R^q。
Author(s): Hirsch, MW | Abstract: Assume n,k,m,q are positive integers. Let M^n denote a smooth differentiable n-manifold and R^k Euclidean k-space. (a) If M^n is open it imbeds smoothly in R^k, k=2n-1 (b) If M^n is open and parallelizable it immerses in R^n (c) Assume M^n is closed and (m-1)-connected, 1l 2m-n l n+1. If a neighborhood of the (n-m)-skeleton immerses in R^q, ag2n-2m, then the complement of a point of M^n imbeds smoothly in R^q.
