Singularities of Null Hypersurfaces of Pseudonull Curves [PDF]

Journal of Function Spaces, 2015
The main goal of this paper is to study the singularities of null hypersurfaces of pseudonull curves. To do this we construct a null frame and a Lorentz distance-squared function of the pseudonull curve.

On partially null and pseudo null curves in the semi-euclidean space $$ R^{4}_{2} $$ [PDF]

Journal of Geometry, 2006
In this paper, we obtain the Frenet equations of a pseudo null and a partially null curves, lying fully in the semi–Euclidean space $$ R^{4}_{2} $$ , and classify all such curves with constant curvatures.

SOME CHARACTERIZATIONS OF NULL, PSEUDO NULL AND PARTIALLY NULL RECTIFYING CURVES IN MINKOWSKI SPACE-TIME

Taiwanese Journal of Mathematics, 2008
In this paper, we define rectifying curves in Minkowski space-time and characterize null, pseudo null and partially null rectifying curves in terms of their curvatures. Also, we give some explicit equations of null, pseudo null and partially null rectifying curves in $E^4_1$.

Moving Null Curves and Integrability [PDF]

Mathematical Methods in the Applied Sciences
ABSTRACT We study the null curves and their motion in 3‐dimensional flat space‐time . We show that when the motion of null curves forms two surfaces in , the integrability conditions lead to the well‐known Ablowitz–Kaup–Newell–Segur (AKNS) hierarchy.

ON NULL CURVES ON SURFACES AND NULL VECTORS IN LORENTZ SPACE

Süleyman Demirel Üniversitesi Fen-Edebiyat Fakültesi Fen Dergisi, 2009
: In this work, we compare the Darboux frame and the Frenet frame of a null curve lying on a spacelike surface in the three-dimensional Lorentz space, and we show that the normal curvature of the curve is a constant.

No Null-Helix Mannheim Curves in the Minkowski Space E13 [PDF]

International Journal of Mathematics and Mathematical Sciences, 2011
We study a null Mannheim curve with time-like or space-like Mannheim partner curve in the Minkowski 3-space E13. We get the characterization of a null Mannheim curve.

Notes on Projective, Contact, and Null Curves

, 2019
These are notes on some algebraic geometry of complex projective curves, together with an application to studying the contact curves in CP^3 and the null curves in the complex quadric Q^3 in CP^4, related by the well-known Klein correspondence. Most of this note consists of recounting the classical background.
