Lorentz流形中允许平行类光向量场的极大超曲面

On maximal hypersurfaces in Lorentz manifolds admitting a parallel lightlike vector field

José A. S. Pelegrín, Alfonso Romero, Rafael M. Rubio

摘要:

本文研究了常中曲率类空超曲面,特别是满足类时收敛条件的p-波时空中的极大超曲面。证明了不存在常中曲率不为零的紧致类空超曲面,并证明了每个紧致极大超曲面都是全测地的。此外,我们还将经典的Calabi-Bernstein定理推广到这类pp波时空。

英文摘要:

We study constant mean curvature spacelike hypersurfaces and in particular maximal hypersurfaces immersed in pp-wave spacetimes satisfying the timelike convergence condition. We prove the non-existence of compact spacelike hypersurfaces whose constant mean curvature is non-zero and also that every compact maximal hypersurface is totally geodesic. Moreover, we give an extension of the classical Calabi-Bernstein theorem to this class of pp-wave spacetimes.
