摘要:

从齐性曲面的等距群出发,讨论CPn中的齐性曲面,得到了CPn中等距群为2维的齐性曲面的分类,并且用李群与活动标价相结合的方法给出了CP2中齐性曲面的分类定理的证明。

关键词: 齐性曲面, 结构方程, 高斯曲率

Abstract: We study the homogeneous surfaces by the method of isometric groups. In this paper, we classify the homogeneous surfaces in CP2 with the isometric transformation group of diemnsion equal to 2 and classify the homogeneous surfaces in CP2 by the methods of Lie groups and moving frames.

Key words: homogeneous surfaces, structure equations, Gaussian curvature
