摘要 该文研究了复射影空间中具有平坦法丛一般子流形的曲率性质与几何性质之间的关系.利用活动标架法,得到关于截面曲率,Ricci曲率和第二基本形式模长的刚性定理,推广和完善了已有文献的相关结果. In this paper, the authors study the relation between properties on curvature and geometry of generic submanifolds with flat normal bundle in a complex projective space. By using the moving-frame method, the rigidity theorems on sectional curvature, Ricci curvature and the length of second fundamental form are obtained, which generalize and improve some results in the relevant literatures.
