We investigate the Lorentzian rigged structure on null hypersurfaces of a Lorentzian
manifold and obtain the necessary and sufficient conditions for such a structure to represent …

In this work, we introduce the notion of constant angle null hypersurface of a Lorentzian
manifold with respect to a given ambient vector field. We analyze the case in which the …

In this paper, we study the geometry of null hypersurface in Lorentzian manifolds furnished
with a conformal vector field W with special attention paid to conformally stationary …

Null hypersurfaces are important objects of study both from the perspective of General
Relativity and semi-Riemannian geometry. In this work, we review the general setting …

We define and study the hypersurfaces in the title, showing that under suitable conditions
they have at most two different non-zero screen principal curvatures. In the case of having …

This work is concerned with the study of the geometry of null hypersurfaces in spacetimes
with certain symmetries. The main drawback of studying null hypersurfaces is the …
