Have we already detected astrophysical symptoms of space-time noncommutativity ? [PDF]

open access: yes, 2001
We discuss astrophysical implications of $\kappa$-Minkowski space-time, in which there appears space-time noncommutativity. We first derive a velocity formula for particles based on the motion of a wave packet.

The Minkowski problem in Gaussian probability space [PDF]

open access: yesAdvances in Mathematics, 2020
The Minkowski problem in Gaussian probability space is studied in this paper. In addition to providing an existence result on a Gaussian-volume-normalized version of this problem, the main goal of the current work is to provide uniqueness and existence ...

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.

Analytic structure of QCD propagators in Minkowski space [PDF]

open access: yes, 2016
Analytical functions for the propagators of QCD, including a set of chiral quarks, are derived by a one-loop massive expansion in the Landau gauge, deep in the infrared.

The Global Nonlinear Stability of Minkowski Space for Self-gravitating Massive Fields [PDF]

open access: yesCommunications in Mathematical Physics, 2015
The Hyperboloidal Foliation Method (introduced by the authors in 2014) is extended here and applied to the Einstein equations of general relativity. Specifically, we establish the nonlinear stability of Minkowski spacetime for self-gravitating massive ...

Advances in solving the two-fermion homogeneous Bethe-Salpeter equation in Minkowski space [PDF]

open access: yes, 2016
Actual solutions of the Bethe-Salpeter equation for a two-fermion bound system are becoming available directly in Minkowski space, by virtue of a novel technique, based on the so-called Nakanishi integral representation of the Bethe-Salpeter amplitude ...

The dimensional Brunn–Minkowski inequality in Gauss space [PDF]

open access: yesJournal of Functional Analysis, 2020
Let $\gamma_n$ be the standard Gaussian measure on $\mathbb{R}^n$. We prove that for every symmetric convex sets $K,L$ in $\mathbb{R}^n$ and every $\lambda\in(0,1)$, $$\gamma_n(\lambda K+(1-\lambda)L)^{\frac{1}{n}} \geq \lambda \gamma_n(K)^{\frac{1}{n}}+(

On Evolutes of Null Cartan Curves in Minkowski 4-Space

open access: yesJournal of New Theory, 2021
This paper aims to discuss the theory of evolutes of null Cartan curves in Minkowski 4-space. In the second part, we present the basic concepts of curves in Minkowski 4-space with its Frenet equations.

Special helices on equiform differential geometry of timelike curves in E_1^4

open access: yesCumhuriyet Science Journal, 2021
In this paper, we introduce the moving Frenet frame along the timelike curve in E_1^4 and then Frenet formulas with the equiform parameter in the equiform geometry of the Minkowski space-time.

Kappa-deformed Snyder spacetime [PDF]

open access: yes, 2009
We present Lie-algebraic deformations of Minkowski space with undeformed Poincare algebra. These deformations interpolate between Snyder and kappa-Minkowski space. We find realizations of noncommutative coordinates in terms of commutative coordinates and
