伪黎曼流形的极小子流形与调和映射

Minimal Submanifolds and Harmonic Maps in Pseudo-Riemannian Manifold

本文讨论伪欧氏空间中位置向量 x 满足 △x=λx 的子流形,并把一些结论推广到伪黎曼流形之间的光滑映射。

Discusses the submanifolds to which the position vector x in a pseudo Eucli-dean space satisfies Δx=λx. Some conclusions are thus generalized available to thesmooth mapping between pseudo Riemannian manifolds.
