摘要
利用Yau极大值原理,研究常曲率空间中具有常平均曲率的正常2-调和完备子流形,得到该类子流形第二基本形式模长平方的一个间隙性质.
The proper biharmonic complete submanifolds with constant mean curvature in constant-curva- ture space were studied by using Yau maximum principle. A gap property of squared model length of sec- ond fundamental form of this class of submanifolds was obtained.
