Conformal and Geodesic Mappings onto Some Special Spaces

open access: yesMathematics, 2019
In this paper, we consider conformal mappings of Riemannian spaces onto Ricci-2-symmetric Riemannian spaces and geodesic mappings of spaces with affine connections onto Ricci-2-symmetric spaces.

Invariants for Second Type Almost Geodesic Mappings of Symmetric Affine Connection Space

open access: yesMathematics
This paper presents the results concerning a space of invariants for second type almost geodesic mappings. After discussing the general formulas of invariants for mappings of symmetric affine connection spaces, based on these formulas, invariants for ...

Geodesic Mappings of Semi-Riemannian Manifolds with a Degenerate Metric

open access: yesMathematics, 2022
This article introduces the concept of geodesic mappings of manifolds with idempotent pseudo-connections. The basic equations of canonical geodesic mappings of manifolds with completely idempotent pseudo-connectivity and semi-Riemannian manifolds with a ...

Fundamental theorems of quasi-geodesic mappings of generalized-recurrent-parabolic spaces

open access: yesPracì Mìžnarodnogo Geometričnogo Centru, 2023
In previous papers we studied mappings of pseudo-Riemannian spaces being mutually quasi-geodesic and almost geodesic of the 2nd type. As a result, we arrived at the quasi-geodesic mapping f: (Vn, gij, Fih) → (Vn, gij, Fih) of spaces with an affine ...

Геодезичні відображення коспактних квазі-ейнштейнових просторів

open access: yesPracì Mìžnarodnogo Geometričnogo Centru, 2021
The paper treats geodesic mappings of quasi-Einstein spaces with gradient defining vector. Previously the authors defined three types of these spaces. In the present paper it is proved that there are no quasi-Einstein spaces of special type.

Geodesic Mappings onto Generalized m-Ricci-Symmetric Spaces

open access: yesMathematics, 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

Approximating Fixed Points of Enriched Nonexpansive Mappings in Geodesic Spaces

open access: yesJournal of Function Spaces, 2022
In this paper, we consider the class of enriched nonexpansive mappings in the setting of geodesic spaces. We obtain a number of fixed point theorems for these mappings in geodesic spaces.

Two Invariants for Geometric Mappings

open access: yesAxioms, 2022
Two invariants for mappings of affine connection spaces with a special form of deformation tensors are obtained in this paper. We used the methodology of Vesić to obtain the form of these invariants.

On geodesic mappings of symmetric pairs

open access: yesPracì Mìžnarodnogo Geometričnogo Centru, 2023
The paper treats properties of pseudo-Riemannian spaces admitting non-trivial geodesic mappings. A symmetric pair of pseudo-Riemannian spaces is a pair of spaces with coinciding values of covariant derivatives for their Riemann tensors. It is proved that

Some fixed-point theorems of convex orbital ( α , β ) $(\alpha, \beta )$ -contraction mappings in geodesic spaces

open access: yesFixed Point Theory and Algorithms for Sciences and Engineering, 2023
The aim of this paper is to broaden the applicability of convex orbital ( α , β ) $(\alpha, \beta )$ -contraction mappings to geodesic spaces. This class of mappings is a natural extension of iterated contraction mappings.
