In this paper, we introduce k-Ricci curvature and k-scalar curvature on lightlike hypersurfaces of a GRW spacetime. Using these curvatures, we establish some inequalities for lightlike hypersurfaces of a GRW spacetime. Using these inequalities, we obtain some characterizations on lightlike hypersurfaces. We also get Chen–Ricci inequality and Chen inequality on a screen homothetic lightlike hypersurfaces of a GRW spacetime.

GRW时空类光超曲面上的陈不等式

在本文中,我们介绍ķ-里奇曲率和ķ-GRW 时空类光超曲面上的标量曲率。使用这些曲率,我们为 GRW 时空的类光超曲面建立了一些不等式。使用这些不等式,我们获得了类光超曲面的一些特征。我们还在 GRW 时空的银幕类光类超曲面上得到 Chen-Ricci 不等式和 Chen 不等式。
