On Bishop frame of a partially null curve in Minkowski space-time E^4_1 [PDF]
In this paper, we introduce Bishop frame of a partially null curve α in Minkowski space-time E41. We prove that such curve has three Bishop frames determined by the particular solutions of the third order non-linear differential equation.

Memory Effect for Impulsive Gravitational Waves
, 2018 International audienceImpulsive gravitational plane waves, which have a δ-function singularity on a hypersurface, can be obtained by squeezing smooth plane gravitational waves with a Gaussian profile.

LIGHTLIKE REAL HYPERSURFACES WITH TOTALLY UMBILICAL SCREEN DISTRIBUTIONS [PDF]
Communications of the Korean Mathematical Society, 2010 The author studies the geometry of lightlike real hypersurfaces of an indefinite Kähler manifold. The main result is a characterization theorem for lightlike real hypersurfaces \(M\) of an indefinite complex space form \(\overline M(c)\) such that the screen distribution is totally umbilic.

Lightlike Hypersurfaces On Manifolds Endowed With A Conformal Structure Of Lorentzian Signature
, 2008 . The authors study the geometry of lightlike hypersurfaces on manifolds (M; c) endowed with a pseudoconformal structure c = CO(n \Gamma 1; 1) of Lorentzian signature.

Lightlike hypersurfaces of a semi-Riemannian manifold with a semi-symmetric metric connection
, 2007 COKEN, A.Ceylan/0000-0002-2727-8665WOS: 000252609000002In this study, we show that the connection induced on a lightlike hypersurface of a semi-Riemannian manifold with a semi-symmetric metric connection is semi-symmetric but not a metric connection and ...
