Some New Algebraic and Topological Properties of the Minkowski Inverse in the Minkowski Space [PDF]

open access: yesThe Scientific World Journal, 2013
We introduce some new algebraic and topological properties of the Minkowski inverse A⊕ of an arbitrary matrix A∈Mm,n (including singular and rectangular) in a Minkowski space μ.

Geometric analysis of non-degenerate shifted-knots Bézier surfaces in Minkowski space. [PDF]

open access: yesPLoS ONE
In this paper, we investigate the properties of timelike and spacelike shifted-knots Bézier surfaces in Minkowski space-[Formula: see text]. These surfaces are commonly used in mathematical models for surface formation in computer science for computer ...

Metric field as emergence of Hilbert space [PDF]

open access: yesScientific Reports
First, we explain some ambiguities of spacetime and metric field as fundamental concepts. Then, from the Unruh effect point of view and using the Gelfand–Naimark–Segal construction, we construct an operator as a quanta of acceleration that we call ...

Quark propagator in Minkowski space [PDF]

open access: yesFew-Body Systems, 2019
The analytic structure of the quark propagator in Minkowski space is more complex than in Euclidean space due to the possible existence of poles and branch cuts at timelike momenta.

Brownian Motion in Minkowski Space [PDF]

open access: yesEntropy, 2015
We construct a model of Brownian motion in Minkowski space. There are two aspects of the problem. The first is to define a sequence of stopping times associated with the Brownian “kicks” or impulses.

The equivariant Minkowski problem in Minkowski space [PDF]

open access: yesAnnales de l'Institut Fourier, 2017
The classical Minkowski problem in Minkowski space asks, for a positive function $\phi$ on $\mathbb{H}^d$, for a convex set $K$ in Minkowski space with $C^2$ space-like boundary $S$, such that $\phi(\eta)^{-1}$ is the Gauss--Kronecker curvature at the ...

Hyperbolic vacua in Minkowski space

open access: yesJournal of High Energy Physics
Families of Lorentz, but not Poincare, invariant vacua are constructed for a massless scalar field in 4D Minkowski space. These are generalizations of the Rindler vacuum with a larger symmetry group. Explicit expressions are given as squeezed excitations

Black Holes have Intrinsic Scalar Curvature

open access: yesReports in Advances of Physical Sciences, 2023
The scalar curvature R is invariant under isometric symmetries (distance invariance) associated with metric spaces. Gravitational Riemannian manifolds are metric spaces.

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.

Generalized Spacelike Normal Curves in Minkowski Three-Space

open access: yesMathematics, 2022
Equiform geometry is considered an extension of other geometries. Furthermore, an equiform frame is a generalization of the Frenet frame. In this study, we begin by defining the term “equiform parameter (EQP)”, “equiform frame”, and “equiform formulas ...
