Generalized Ricci solitons on homogeneous Siklos space-times [PDF]

open access: yesAUT Journal of Mathematics and Computing
In this paper, the class of homogeneous Siklos space-times is considered from algebraic point of view and the generalized Ricci solitons are completely classified.

Induced Gauge Fields in the Path Integral [PDF]

open access: yes, 1995
The path integral on a homogeneous space $ G/H $ is constructed, based on the guiding principle `first lift to $ G $ and then project to $ G/H $'.

ON THE ALMOST PERIODIC AT INFINITY FUNCTIONS FROM HOMOGENEOUS SPACES

open access: yesПроблемы анализа, 2018
We consider homogeneous spaces of functions defined on the real axis (or semi-axis) with values in a complex Banach space. We study the new class of almost periodic at infinity functions from homogeneous spaces.

On completely homogeneous c-spaces

open access: yesHeliyon, 2020
In this paper we determine completely homogeneous c-spaces. Various properties of completely homogeneous c-spaces are discussed. Relation between completely homogeneous c-space and hereditary homogeneous c-space is studied.

The nodal cubic is a quantum homogeneous space [PDF]

open access: yes, 2017
The cusp was recently shown to admit the structure of a quantum homogeneous space, that is, its coordinate ring B can be embedded as a right coideal subalgebra into a Hopf algebra A such that A is faithfully flat as a B-module.

Unified representation of homogeneous and quasi-homogenous systems in geometrothermodynamics

open access: yesPhysics Letters B, 2023
We analyze homogeneous and quasi-homogeneous thermodynamic systems within the formalism of geometrothermodynamics (GTD). A generalized Euler identity is used to obtain the explicit form of the three Legendre invariant metrics that are known in GTD for ...

Integrators on homogeneous spaces: Isotropy choice and connections [PDF]

open access: yes, 2016
We consider numerical integrators of ODEs on homogeneous spaces (spheres, affine spaces, hyperbolic spaces). Homogeneous spaces are equipped with a built-in symmetry. A numerical integrator respects this symmetry if it is equivariant.

Concentrated Force Action on 1/8 Homogeneous Isotropic Space

open access: yesНаука и техника, 2020
Using the example of vertical displacements, it is shown that by combining a solution to the problem of determining vertical displacements from the action of four identical concentrated forces symmetrically applied to an elastic half-space and two ...

Le problème régional en géographie

open access: yesGéographie et Cultures, 2016
In the traditional rural countries, it was possible to distinguish areas that were homogeneous by their physical and human features: the regional perspective played an essential role, since it facilitated knowledge and insured a good adminis­tration ...

To Clarify Decision on Action of Concentrated Force to Elastic Quarter-Space for Arbitrary Poisson’s Ratio

open access: yesНаука и техника, 2022
Previously, the author obtained an analytical solution for determining the vertical displacements of the homogeneous isotropic quarter-space face, which is affected by a vertical concentrated force.
