六维伪黎曼空间型中的λ-双调和超曲面
λ-BIHARMONIC HYPERSURFACES IN 6-DIMENSIONAL PSEUDO-RIEMANNIAN SPACE FORMS
摘要
Abstract
In this paper,we study λ-biharmonic hypersurfaces M5r of 6-dimensional pseudo-Riemannian space form N6p(c)with the indexs 0 ≤ p ≤ 6,r=p-1 orp,and constant curvature c.It was proved that if the shape operator of M5r is diagonalizable,then the mean curvature is a constant.As an application,we find some types of biharmonic hypersurfaces of N6p(c)are minimal.关键词
