A Brief Remark on Energy Conditions and the Geroch-Jang Theorem [PDF]

open access: yes, 2011
The status of the geodesic principle in General Relativity has been a topic of some interest in the recent literature on the foundations of spacetime theories.

Generating Geodesic Flows and Supergravity Solutions [PDF]

open access: yes, 2009
We consider the geodesic motion on the symmetric moduli spaces that arise after timelike and spacellike reductions of supergravity theories. The geodesics correspond to timelike respectively spacelike p-brane Solutions when they are lifted over a p ...

Generating Generalized Cylinder with Geodesic Base Curve According to Darboux Frame

open access: yesJournal of New Theory, 2021
This paper aims to design a generalized cylinder with a geodesic base curve according to the Darboux frame in Euclidean 3-space. A generalized cylinder is a special ruled surface that is constructed by a continuous fixed motion of a generator line called

Geometry Optimization Speedup Through a Geodesic Approach to Internal Coordinates

open access: yes, 2021
We present a new geodesic-based method for geometry optimization in a basis of redundant internal coordinates. Our method updates the molecular geometry by following the geodesic generated by a displacement vector on the internal coordinate manifold ...

Geodesic motion near self-gravitating scalar field configurations

open access: yesDiscrete and Continuous Models and Applied Computational Science, 2019
We study the geodesics motion of neutral test particles in the static spherically symmetric spacetimes of black holes and naked singularities supported by a selfgravitating real scalar field.

Geodesics in Heat

open access: yesCoRR, 2012
We introduce the heat method for computing the shortest geodesic distance to a specified subset (e.g., point or curve) of a given domain. The heat method is robust, efficient, and simple to implement since it is based on solving a pair of standard linear elliptic problems. The method represents a significant breakthrough in the practical computation of

On geodesic mappings preserving the Einstein tensor [PDF]

open access: yes, 2010
summary:In this paper there are discussed the geodesic mappings which preserved the Einstein tensor. We proved that the tensor of concircular curvature is invariant under Einstein tensor-preserving geodesic ...

Evolutionary dynamics on a regular networked structured and unstructured multi‐population

open access: yesInternational Journal of Robust and Nonlinear Control, EarlyView., 2023
Abstract In this paper, we study collective decision‐making in a multi‐population framework, where groups of individuals represent whole populations that interact by means of a regular network. Each group consists of a number of players and every player can choose between two options.

Conservation Laws and Moving Frame Method of Vaidya-Bonner Space-Time [PDF]

open access: yesSahand Communications in Mathematical Analysis, 2022
In the present paper, we compute the conservation laws  of the Vaidya-Bonner geodesic space-time metric in aRiemannian space and carry out the moving frame  method for this metric.
