Dual Associate Null Scrolls with Generalized 1-Type Gauss Maps
Mathematics, 2020 In this work, a pair of dual associate null scrolls are defined from the Cartan Frenet frame of a null curve in Minkowski 3-space. The fundamental geometric properties of the dual associate null scrolls are investigated and they are related in terms of ...

Position Vector of a Partially Null Curve Derived from a Vector Differential Equation
, 2009 In this paper, position vector of a partially null unit speed curve with respect to standard frame of Minkowski space-time is studied. First, it is proven that position vector of every partially null unit speed curve satisfies a vector differential ...

The Holographic Nature of Null Infinity
SciPost Physics, 2021 We argue that, in a theory of quantum gravity in a four dimensional asymptotically flat spacetime, all information about massless excitations can be obtained from an infinitesimal neighbourhood of the past boundary of future null infinity and does not

Evolutes of plane curves and null curves in Minkowski 3-space [PDF]
Journal of Geometry, 2016 We use the isotropic projection of Laguerre geometry in order to establish a correspondence between plane curves and null curves in the Minkowski $3$-space. We describe the geometry of null curves (Cartan frame, pseudo-arc parameter, pseudo-torsion, pairs of associated curves) in terms of the curvature of the corresponding plane curves.

CONSTRUCTION OF OFFSET SURFACES WITH A GIVEN NON-NULL ASYMPTOTIC CURVE [PDF]
, 2021 In the present work, we study construction of offset surfaces with a givennon-null asymptotic curve. Let $\alpha \left( s\right) $ be a spacelike ortimelike unit speed curve with non-vanishing curvature and $\varphi \left(s,t\right) $ be a surface pencil
