Complete space-like hypersurfaces with constant mean curvature in locally symmetric Lorentz spaces

In this paper, we mainly discuss a kind of surfaces in4- dimensional Pseudo-Euclidean Space and give the classification of such surfaces with constant mean curvature and Gauss curvature.

This paper discusses the space-like submanifolds with constant mean curvature in a pseudo-Riemannian space form, and obtain an integrate inequality and a rigidity theorem.

With respect to the special case,in which some algorithm cannot handle at all, of regions with the Gaussian curvature closes to zero and the absolute mean curvature is greater than some threshold,this method can efficiently handle and its speed is very fast.

The compact totally real submanifolds with parallel mean curvature vector in complexprojective space are studied, and a gap intervai about the length square of these submanifolde secondfundanwntal form is obtained.

The study of2- harmonic space-like submanifolds in pseudo-Riemiann manifold has a sufficient condiction for the minimal submanifolds, which generalizes OUYANG Chong-zhen' s results of2- harmonic submanifolds in pseudo-Riemiann manifold with parallel mean curvature vector.
