In the last two sections we deal with the basic results on null curves and lightlike hypersurfaces of 4 dimensional Lorentz : Krishan L. Duggal, Ramesh Sharma.
We study lightlike hypersurfaces of a semi-Riemannian product manifold. We introduce a class of lightlike hypersurfaces called screen semi-invariant lightlike hypersurfaces and radical anti-invariant lightlike hypersurfaces.

Lightlike Hypersurfaces of Semi-Riemannian Manifolds. Some work is known on null hypersurfaces and degenerate submanifolds (see an up-to-date list of references on pages and respectively).
Our approach, in this book, has the following outstanding features: (a) It is the first-ever attempt of an up-to-date information on null curves, lightlike hypersur faces and submanifolds, consistent.

Duggal,available at Book Depository with free delivery worldwide. The theory of Riemannian and semi-Riemannian manifolds (M, g) and their submanifold is one of the most interesting areas of research in differential geometry.
Most of the work on the Riemannian, semi-Riemannian, and Lorentzian manifolds has been described in the standard books by Chen [1], Beem and Ehrlich [2], and O’Neill [3].Berger’s book [4] includes the major developments of Riemannian.
This is a review paper of up-to-date research done on the existence of unique null curves, screen distributions, Levi-Civita connection, symmetric Ricci tensor, and scalar curvature for a large variety of lightlike submanifolds of semi-Riemannian (in particular, Lorentzian) manifolds, supported by examples and an extensive bibliography.

On focal curves of null Cartan curves Hakan S˘IMS˘EK_ the general study of the geometry of null curves in Lorentz manifolds and, more generally, in semi-Riemannian manifolds (see also the book [5]). Ferrandez et al. [6] gave a reference along a null curve in an n-dimensional. Given a null hypersurface of a Lorentzian manifold, we induce a Riemannian metric on the null hypersurface using a normalizing field defined on some open set containing the null : Karimumuryango M.
For instance, Duggal and Jin have systematic studied the null curves in semi-Riemannian manifolds and proved the existence of a canonical representation of null curves on Lorentzian manifolds.
Bejancu provides a general method to study the geometry of null curves on Lorentzian manifolds in. We will employ these methods to investigate the Author: Sining Wei, Jie Huang, Liang Chen.

In this article, we define Lorentzian cross product in a three-dimensional almost contact Lorentzian manifold. Using a Lorentzian cross product, we prove that the ratio of κ and τ − 1 is constant along a Frenet slant curve in a Sasakian Lorentzian three-manifold.
Moreover, we prove that γ is a slant curve if and only if M is Sasakian for a contact magnetic curve γ in contact Cited by: 1.

Also, we obtain some geometric properties of lightlike hypersurfaces with a conformal Killing distribution.
Introduction. The notion of being totally umbilic is considered for non-degenerate and degenerate submanifolds of semi-Riemanian manifolds. After some remarks on the general case, timelike and lightlike totally umbilic submanifolds of Lorentzian manifolds are discussed, along with their physical interpretation in view of general relativity.
In particular, the mathematical notion of totally umbilic. Null curves and hypersurfaces of semi-Riemannian manifolds. World Scientific. Duggal, Krishan L., Jin, Dae Ho.
