BIHARMONIC SPACE-LIKE SUBMANIFOLDS IN PSEUDO-RIEMANNIAN SPACE FORMS
摘要
Abstract
In this paper, we study the biharmonic space-like submanifolds in the pseudo-Riemannian space form. By using moving-frame method and Hopf lemma, we prove that any pseudo-umbilical biharmonic space-like submanifold Mn is maximal, and show that if Mn is compact, then it is totally geodesic, which generalizes results in [5, 7].关键词
