Right Conoids Demonstrating a Time-like Axis within Minkowski Four-Dimensional Space

open access: yesMathematics
In the four-dimensional Minkowski space, hypersurfaces classified as right conoids with a time-like axis are introduced and studied. The computation of matrices associated with the fundamental form, the Gauss map, and the shape operator specific to these

The dual conformal box integral in Minkowski space

open access: yesNuclear Physics B, 2021
The dual conformal box integral in Minkowski space is not fully determined by the conformal invariants z and z¯. Depending on the kinematic region its value is on a ‘branch’ of the Bloch-Wigner function which occurs in the Euclidean case.

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.

Darboux Vector in Four-Dimensional Space-Time

open access: yesAdvances in Mathematical Physics, 2022
As the space-time model of the theory of relativity, four-dimensional Minkowski space is the basis of the theoretical framework for the development of the theory of relativity.

Singularities of lightlike hypersurfaces in Minkowski four-space [PDF]

open access: yesTohoku Mathematical Journal, 2006
The authors classify the singularities of light-like hypersurfaces in Minkowski space, in terms of the contact invariants for space-like surfaces and lightcones. They use the Lorentzian distance-squared function on space-like surfaces and Montaldi's characterization of submanifolds contact in terms of \(\mathcal K\)-equivalence.

Role of time in implementation of innovative technologies [PDF]

open access: yesMATEC Web of Conferences, 2021
Time is considered as production resource, which determines the need for its effective use in connection with other production resources. The problem consists in the inconsistency of the results of the existing forecasting system of production which are ...

Massive spinning bosons on the celestial sphere

open access: yesJournal of High Energy Physics, 2020
A natural extension of the Pasterski-Shao-Strominger (PSS) prescription is described, enabling the map of Minkowski space amplitudes with massive spinning external legs to the celestial sphere to be performed. An integral representation for the conformal

Timelike rotational hypersurfaces with timelike axis in Minkowski four-space

open access: yesCommunications Faculty Of Science University of Ankara Series A1Mathematics and Statistics, 2023
We introduce the timelike rotational hypersurfaces $\textbf{x}$ with timelike axis in Minkowski 4-space $\mathbb{E}_1^{4}$. We obtain the equations for the curvatures of the hypersurface. Moreover, we present a theorem for the rotational hypersurfaces with timelike axis supplying $\Delta\textbf{x}=\mathcal{T}\textbf{x}$, where $\mathcal{T}$ is a 4x4 ...

Time as a geometric property of space

open access: yesFrontiers in Physics, 2016
The proper description of time remains a key unsolved problem in science. Newton conceived of time as absolute and universal which it `flows equably without relation to anything external'}.
