On some conformally einstein manifolds of dimension four [PDF]

ریاضی و جامعه, 2022
We study an important family of four-dimensional pseudo-Riemannian manifolds, i.e. generalized symmetric spaces, in terms of conformal geometry. Generalized symmetric spaces were introduced by geometers as an extension of symmetric spaces, and a detailed

Geodesic Ricci-symmetric pseudo-Riemannian spaces

Pracì Mìžnarodnogo Geometričnogo Centru, 2022
We introduced special pseudo-Riemannian spaces, called geodesic A-symmetric spaces, into consideration. It is proven that there are no geodesic symmetric spaces and no geodesic Ricci symmetric spaces, which differ from spaces of constant curvature and ...

Canonical Almost Geodesic Mappings of the First Type of Spaces with Affine Connections onto Generalized m-Ricci-Symmetric Spaces

Mathematics, 2021
In the paper we consider almost geodesic mappings of the first type of spaces with affine connections onto generalized 2-Ricci-symmetric spaces, generalized 3-Ricci-symmetric spaces, and generalized m-Ricci-symmetric spaces.

Application of symmetric analytic functions to spectra of linear operators

Karpatsʹkì Matematičnì Publìkacìï, 2021
The paper is devoted to extension of the theory of symmetric analytic functions on Banach sequence spaces to the spaces of nuclear and $p$-nuclear operators on the Hilbert space.

Compactifications of symmetric and locally symmetric spaces [PDF]

Mathematical Research Letters, 2002
Let \(G\) be a connected non-compact linear real semisimple Lie group, \(K\) a maximal compact subgroup of \(G\), and \(\Gamma\) an arithmetically defined not co-compact subgroup of \(G\). The authors define several known compactifications of \(G\): \(X=G/K\), \(\Gamma\backslash G\) and \(\Gamma\backslash X\), Satake compactifications of \(X=G/K\) and ...

Geodesic Mappings onto Generalized m-Ricci-Symmetric Spaces

Mathematics, 2022
In this paper, we study geodesic mappings of spaces with affine connections onto generalized 2-, 3-, and m-Ricci-symmetric spaces. In either case, the main equations for the mappings are obtained as a closed system of linear differential equations of the
