定理设M-x微分嵌入在n维微分流形N中,使得嵌入的法丛是纤维同伦平凡的。然后有一个到smash积N-->Sn-m A M上的一次映射。(The如果M或N不可定向,则次数取模2;如果N不紧或有界,则次数取关于NBd N的紧上同调的模2。
THEOREM. Let M-x be embedded differentially in a differential manifold N of dimension n, in such a way that the normal bundle of the embedding is fibre homotopically trivial. Then there is a map of degree one onto the smash product N-->Sn-m A M. (The degree should be taken mod 2 if M or N is not orientable, and with respect to the compact cohomology of NBd N if N is not compact or has boundary.)
