Are There Any Natural Physical Interpretations for Some Elementary Inequalities?

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2022
We inquire whether there are some fundamental interpretations of elementary inequalities in terms of curvature of a three-dimensional smooth hypersurface in the four-dimensional real ambient space.

Particle Motion in Monopoles and Geodesics on Cones [PDF]

, 2014
. The equations of motion of a charged particle in the field of Yang’s SU(2) monopole in 5-dimensional Euclidean space are derived by applying the Kaluza–Klein for-malism to the principal bundle R8 \{0} → R5 \{0} obtained by radially extending the Hopf ...

Elastic Sturmian spirals in the Lorentz-Minkowski plane

Open Mathematics, 2016
In this paper we consider some elastic spacelike and timelike curves in the Lorentz-Minkowski plane and obtain the respective vectorial equations of their position vectors in explicit analytical form.

Bobillier Formula for the Elliptical Harmonic Motion

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2018
In this study, we have considered the elliptical harmonic motion which is the superposition of two simple harmonic motions in perpendicular directions with the same angular frequency and phase difference of π/2 .

On the geometric nature of the twin paradox in curved spacetimes

Demonstratio Mathematica, 2017
The famous „twin paradox” of special relativity is of purely geometric nature and formulated in curved spacetimes of general relativity motivates investigations of the timelike geodesic structure of these manifolds.

On Twisted Spacetimes: a new class of Galilean cosmological models

Advanced Nonlinear Studies
Within the generalized Newton-Cartan theory, Galilean Twisted spacetimes are introduced as dual models of the well-known relativistic twisted spacetimes.

Construction of new curves on nth degree polynomial-type curves using the Flc frame

Demonstratio Mathematica
In this study, first, the pedal curves were defined as the geometric locus of perpendicular projections onto the Frenet-like frame (Flc) vectors T, D 2, and D 1 of a given polynomial curve.

Symmetry and pseudosymmetry properties with Ricci soliton of the Reissner-Nordström-de Sitter spacetime

Nuclear Physics B
The primary objective of the article is to investigate the symmetry and pseudosymmetry properties of the Reissner-Nordström-de Sitter (briefly, RNdS) spacetime. The secondary aim of the paper is to explore the notion of Ricci solitons in RNdS spacetimes.
