Tangent Spaces of Minkowski Spaces
Missouri Journal of Mathematical Sciences, 2003 The author' work on the class of centrally convex compact bodies whose centre is the origin in the \(n\)-dimensional real space. The main result concerns the tangent spaces of Minkowski spaces: Let \(U_i\), and \(U\) be the indicatrices of \(M^n(U_i)\) and \(M^n(U)\).

Hyperbolic vacua in Minkowski space
Journal of High Energy PhysicsFamilies 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
Reports 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
Nuclear 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
Mathematics, 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 ...

The equivariant Minkowski problem in Minkowski space [PDF]
Annales de l’institut Fourier, 2017 The classical Minkowski problem in Minkowski space asks, for a positive function $ $ on $\mathbb{H}^d$, for a convex set $K$ in Minkowski space with $C^2$ space-like boundary $S$, such that $ ( )^{-1}$ is the Gauss--Kronecker curvature at the point with normal $ $.

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

Renormalization in Minkowski space–time [PDF]
International Journal of Modern Physics A, 2021 The multiplicative and the functional renormalization group methods are applied for the four-dimensional scalar theory in Minkowski space–time. It is argued that the appropriate choice of the subtraction point is more important in Minkowski than in Euclidean space–time.

Intent Arabic text categorisation based on different machine learning and term frequency
IET Networks, EarlyView., 2022 Abstract The complexity of Internet network configurations has made managing networks a complicated undertaking. Intent‐Based Networking (IBN) is a potential solution to this issue. In contrast to conventional networks, where a concrete description of the settings typically conveys a network administrator's goal kept on each device, an administrator's ...

Inflation from Minkowski space [PDF]
Journal of High Energy Physics, 2014 We propose a class of scalar models that, once coupled to gravity, lead to cosmologies that smoothly and stably connect an inflationary quasi-de Sitter universe to a low, or even zero-curvature, maximally symmetric spacetime in the asymptotic past, strongly violating the null energy condition ($\dot H\gg H^2$) at intermediate times.
