Electromagnetic waves along pseudo null curves in Minkowski space [PDF]

open access: yesHeliyon, 2022
Considering the importance of Minkowski space in physics, it is an incomplete approach to deal with EM waves only in Euclidean space. For this reason, this paper deals with EM waves along pseudo null curves in Minkowski space.

Involutes of Pseudo-Null Curves in Lorentz–Minkowski 3-Space

open access: yesMathematics, 2021
In this paper, we analyze involutes of pseudo-null curves in Lorentz–Minkowski 3-space. Pseudo-null curves are spacelike curves with null principal normals, and their involutes can be defined analogously as for the Euclidean curves, but they exhibit ...

Null Darboux Curve Pairs in Minkowski 3-Space

open access: yesAxioms, 2021
Based on the fundamental theories of null curves in Minkowski 3-space, the null Darboux mate curves of a null curve are defined which can be regarded as a kind of extension for Bertrand curves and Mannheim curves in Minkowski 3-space.

Structure Functions of Pseudo Null Curves in Minkowski 3-Space

open access: yesMathematics, 2020
In this work, the embankment surfaces with pseudo null base curves are investigated in Minkowski 3-space. The representation formula of pseudo null curves is obtained via the defined structure functions and the k-type pseudo null helices are discussed ...

Some characterizations of null osculating curves in the Minkowski space-time; pp. 1–8 [PDF]

open access: yesProceedings of the Estonian Academy of Sciences, 2012
In this paper we give the necessary and sufficient conditions for null curves in E41 to be osculating curves in terms of their curvature functions. In particular, we obtain some relations between null normal curves and null osculating curves as well as ...

On Characterizations of W-Directional Curves of Null Curves in Minkowski 4-Space

open access: yesSüleyman Demirel Üniversitesi Fen-Edebiyat Fakültesi Fen Dergisi, 2022
In the present paper, we investigate the casual characterizations of W-directional curves of null curves in Minkowski 4-space. In section two, the basic concepts of curves with their Frenet equations in Minkowski 4-space are provided.

Inextensible Flows of Null Cartan Curves in Minkowski Space R2,1

open access: yesUniverse, 2023
This research focused on studying the flows of a null Cartan curve specified by the velocity and acceleration fields. We have proven that the tangential and normal velocities are influenced by the binormal velocity along the motion.

Some Characteristic Properties of Non-Null Curves in Minkowski 3-Space 𝔼13

open access: yesMathematics, 2023
This paper gives new characteristic properties of non-null spherical and rectifying curves in Minkowski 3-space E13. In the light of the causal characteristics, we give some representations of rectifying non-null curves.

open access: yesJournal of Inequalities and Applications, 2020
In this paper, we investigate the representation of curves on the lightlike cone Q 2 3 $\mathbb {Q}^{3}_{2}$ in Minkowski space R 2 4 $\mathbb {R}^{4}_{2}$ by structure functions.
