关于负常曲率的伪黎曼流形的2-调和子流形的注记

NOTE ON 2-HARMONIC SPACE-LIKE SUBMANIFOLDS OF A PSEUDO-RIEMANNIAN MANIFOLD OF NEGATIVE CONSTANT CURVATURE

用活动标架法给出了负常曲率的伪黎曼流形的 2 -调和子流形成为极大类空子流形的充分条件。

The paper gives some conditions that a 2-harmonic space-like submanifole of a pseudo-Riemannian manifold of negative constant curvature is a maximal space-like submanifold.
