Frames and Homogeneous Spaces [PDF]

open access: yesJournal of Sciences, Islamic Republic of Iran, 2011
Let be a locally compact non?abelian group and be a compact subgroup of also let be a ?invariant measure on the homogeneous space . In this article, we extend the linear operator as a bounded surjective linear operator for all ?spaces with .

Geodesic vectors of square metrics on 5- dimensional generalized symmetric spaces [PDF]

open access: yesریاضی و جامعه
In this paper, we consider the $(\alpha, \beta)$-metric $F=\frac{(\alpha + \beta)^2}{\alpha}$ along with the function $\phi$ with the definition of $\phi(s)=1+2s+s^2$, which is known as a square metric, on 5-dimensional generalized symmetric spaces. Then

Multilinear strongly singular integral operators on non-homogeneous metric measure spaces

open access: yesJournal of Inequalities and Applications, 2022
Let ( X , d , μ ) $(X,d,\mu )$ be a non-homogeneous metric measure space satisfying the geometrically and upper doubling measure conditions. In this paper, the boundedness in Lebesgue spaces for multilinear strongly singular integral operators on non ...

Minimal Immersions of Kahler manifolds into Euclidean Spaces [PDF]

open access: yes, 2003
It is proved here that a minimal isometric immersion of a Kähler-Einstein or homogeneous Kähler-manifold into an Euclidean space must be totally ...

Compact Riemannian Manifolds with Homogeneous Geodesics

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2009
A homogeneous Riemannian space (M = G/H,g) is called a geodesic orbit space (shortly, GO-space) if any geodesic is an orbit of one-parameter subgroup of the isometry group G. We study the structure of compact GO-spaces and give some sufficient conditions

Sigma-models with complex homogeneous target spaces

open access: yesEPJ Web of Conferences, 2016
We review the recently proposed class of σ-models with complex homogeneous target spaces, whose equations of motion admit zero-curvature representations.

More on the cardinality of a topological space

open access: yesApplied General Topology, 2018
In this paper we continue to investigate the impact that various separation axioms and covering properties have onto the cardinality of topological spaces. Many authors have been working in that field.

On the Volume in Homogeneous Spaces [PDF]

open access: yesNagoya Mathematical Journal, 1959
Guldin-Pappus’s theorem about the volume of a solid of rotation in the euclidean space has been generalized in two ways. G. Koenigs [1] and J. Hadamard [2] proved that the volume generated by a 1-parametric motion of a surface D bounded by a closed curve c is equal to where are quantities attached to D with respect to a rectangular coordinate system ...

Fourier Transform on the Homogeneous Space of 3D Positions and Orientations for Exact Solutions to Linear PDEs

open access: yesEntropy, 2019
Fokker–Planck PDEs (including diffusions) for stable Lévy processes (including Wiener processes) on the joint space of positions and orientations play a major role in mechanics, robotics, image analysis, directional statistics and ...
