摘要
设N是欧氏空间En + 1中的超曲面 ,M是N的子流形 .在子流形的高斯映照 (Ⅰ )的基础上 ,计算了M上高斯映照的截面曲率 ,讨论了当外围空间N为Dupin超曲面时 。
WT5BZ]Let N be a hypersurface of the Euclidean space E n+1 , and M be a submanifold isometrically immersed in N . In this paper, we calculate the sectional curvatures of the Gauss map of M is calculated and the Gauss map of submanifolds immersed in Dupin hypersurfaces is studied.
