摘要
讨论局部对称共形平坦伪黎曼流形的2-调和类空子流形,得到这类子流形成为极大的二个充分条件,推广了文[2]中的结论.
In this paper, we discuss the 2-harmonic spacelike submanifolds in a locally symmetric and conformally flat pseudo-riemannian manifold and get two sufficient conditions under which Mn turns into a maximal submanifold,and the results in [2] are improved.
