摘要: 利用活动标架法研究2-调和全实子流形, 得到了两个Pinching定理. 结果表明, 在局部对称BochnerKaehler流形中不存在具有平行平均曲率且截面曲率大于零的全实2-调和子流形.

关键词: 全实子流形, 2-调和, 全纯截面曲率

Abstract: We studied totally real 2-harmonic submanifolds by moving frame, obtained two pinching theorems. We have discovered that there are no compact totally real 2-harmonic submanifolds with parallel mean curvature and positive curvature in a locally symmetric BochnerKaehler manifold.

Key words: totally real submanifold, 2-harmonic, holomorphic se ctional curvature
