affine surface

用法例句

The author studied centroaffine hypersurfaces in (n+1) dimensional Euclidean space R n+1 and obtained the results for the uniqueness and existence of centroaffine hypersurfaces.

本文作者研究了 (n + 1)维欧氏空间Rn+1中的中心仿射超曲面 ,得到了中心仿射超曲面的唯一性和存在性两个结

In this paper, we will first introduce connection form g and cubic form A, then westudied centroaffine hypersurfaces in (n + 1) -dimensional affinespace An+1 and got the uniqueness and existence of centroaffinehypersurfaces.

对任意超曲面浸入x：M→A~(n+1)，若位置矢量x横截于点x处的切平面x_*(TM)，则TM上存在在中心仿射变换群G作用下不变的对称的双线性形式g和对称的三次协变形式A，如果g非退化，我们则称x为中心仿射超曲面。
