纯微分 meaning in Chinese
pure differential
Examples
- In 1951 , h . hopf proved , by associating a holomorphic 2 - differential to each constant mean curvature surfaces in r3 , that only compact genus zero surfaces immersed in r3 with constant mean curvature are the round sphere , in chapter two , we consider the same question about the compact 2 - type surfaces of genus zero in s7
1951年， h . hopf发现r ~ 3中每个常平均曲率曲面都伴随一个全纯微分2 -形式，并证明了零亏格的常平均曲率闭曲面一定是r3中的球面.本文的第二章对于犷中零亏格的2型曲面讨论了类似的问题
