How can we determine if a spacetime is flat?

open access: yesFrontiers in Physics, 2013
A spacetime is locally flat if and only if no geodesical deviation exists for congruences of all kinds of geodesics. However, while for causal geodesics the deviation can be measured observing the motion of (infinitesimal) falling bodies, it does not

Geodesics in the TPS Space

open access: yesMathematics, 2022
In shape analysis, the interpolation of shapes’ trajectories is often performed by means of geodesics in an appropriate Riemannian Shape Space. Over the past several decades, different metrics and shape spaces have been proposed, including Kendall shape ...

Remarks on Wiener Index of Bipolar Fuzzy Incidence Graphs

open access: yesFrontiers in Physics, 2021
Fuzzy data plays an important role in daily life, and fuzzy structured data is usually represented by fuzzy graphs, where the graph structure is used to describe the associated structure of the fuzzy data.

Duality on Geodesics of Cartan Distributions and Sub-Riemannian Pseudo-Product Structures

open access: yesDemonstratio Mathematica, 2015
Given a five dimensional space endowed with a Cartan distribution, the abnormal geodesics form another five dimensional space with a cone structure. Then it is shown in (15), that, if the cone structure is regarded as a control system, then the space of ...

Length Modelling of Spiral Superficial Soft Strain Sensors Using Geodesics and Covering Spaces

open access: yesRobotics, 2023
Piecewise constant curvature soft actuators can generate various types of movements. These actuators can undergo extension, bending, rotation, twist, or a combination of these.

Multiple Closed Geodesics on Positively Curved Finsler Manifolds

open access: yesAdvanced Nonlinear Studies, 2019
In this paper, we prove that on every Finsler manifold (M,F){(M,F)} with reversibility λ and flag curvature K satisfying (λλ+1 ...

Kinematic space for conical defects

open access: yesJournal of High Energy Physics, 2017
Kinematic space can be used as an intermediate step in the AdS/CFT dictionary and lends itself naturally to the description of diffeomorphism invariant quantities.

Geodesics on the Momentum Phase Space with metric $^{{C}}{g}$

open access: yesUniversal Journal of Mathematics and Applications, 2018
In this paper, a system of the differential equations giving geodesics on the momentum phase space with pseudo Riemann metric $^{C}g$ of a Hamilton space is found by using the Euler Lagrange equations.
