在欧氏空间中的余维为2的浸入的反射
Year: 1987 Journal: Science in China Series A-Mathematics Physics Astronomy & Technological Science (in Chinese) Vol: 17 (8)Pages: 793-799 Publisher: Science China Press
Abstract
本文证明了Mn→Rn+2的一个浸入正则同伦于它的反射,当且仅当它的法Euler类是零. 同时给出了Mn→Rm(m>n)具有等价法丛的浸入的分类定理;证明了一个2维向量丛有反向自同构的充分必要条件是它的Euler类模2等于零.
