Celestial holography and AdS 3/CFT 2 from a scaling reduction of twistor space

open access: yesJournal of High Energy Physics, 2023
Celestial amplitudes obtained from Mellin transforming 4d momentum space scattering amplitudes contain distributional delta functions, hindering the application of conventional CFT techniques.

Loxodromes on twisted surfaces in Lorentz–Minkowski 3-space

open access: yesAsian-European Journal of Mathematics, 2022
In this paper, first, we give the general formulas according to first fundamental form of a surface for different types of loxodromes, meridians and surfaces in [Formula: see text]. After that, we obtain the differential equations of loxodromes on Type-I, Type-II and Type-III twisted surfaces in [Formula: see text] and also, we state a theorem which ...

Spacelike Ac-Slant Curves with Non-Null Principal Normal in Minkowski 3-Space

open access: yesJournal of New Theory, 2023
In this paper, we define a spacelike ac-slant curve whose scalar product of its acceleration vector and a unit non-null fixed direction is a constant in Minkowski 3-space.

Henneberg's algebraic surfaces in Minkowski 3-space

open access: yesCommunications Faculty Of Science University of Ankara Series A1Mathematics and Statistics, 2019
Summary: We consider the Henneberg's algebraic zero mean curvature surfaces in three-dimensional Minkowski space, and compute their classes, degrees and integral free representations. We also draw some figures of the algebraic surfaces.

ON TIMELIKE BERTRAND CURVES IN MINKOWSKI 3-SPACE

open access: yesHonam Mathematical Journal, 2016
Summary: In this paper, we study the timelike Bertrand curves in Minkowski 3-space. Since the principal normal vector of a timelike curve is spacelike, the Bertrand mate curve of this curve can be a timelike curve, a spacelike curve with spacelike principal normal or a Cartan null curve, respectively.

On the Gauss Map of Surfaces of Revolution with Nonlightlike Axis in Minkowski 3-Space

open access: yesAbstract and Applied Analysis, 2014
We study surfaces of revolution with a nonlightlike axis in 3-dimensional Minkowski space and classify such surfaces in terms of the Gauss map G that satisfies the condition ΔhG=ΛG, with Λ being a 3×3 real matrix.

Timelike-Ruled and Developable Surfaces in Minkowski 3-Space E13

open access: yesFrontiers in Physics, 2022
In this study, the timelike-ruled and developable surfaces are constructed in Minkowski 3-space E13. Using the E. Study map, we demonstrate that dual forms of timelike-ruled and developable surfaces can be obtained from the coordinates and first ...

On the Involute-Evolute of the Pseudonull Curve in Minkowski 3-Space [PDF]

open access: yesJournal of Applied Mathematics, 2013
We have generalized the involute and evolute curves of the pseudonull curves in ; that is, is a spacelike curve with a null principal normal. Firstly, we have shown that there is no involute of the pseudonull curves in . Secondly, we have found relationships between the evolute curveβand the pseudonull curve in . Finally, some examples concerning these

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 ...
