摘要: 利用Cartan嵌入和活动标架法研究复格拉斯曼流形G(k,n)中三维SU(2)轨道的几何.

关键词: 全实浸入, 截面曲率, 第二基本形式

Abstract: We use the Cartan embedding and the method of moving frame to study the geometry of 3-dimensional SU(2)-orbits in the complex Grassmann manifold G(k,n).

Key words: totally real immersions, sectional curvature, second fundamental form
