On geodesic mappings in a particular class of Roter spaces [PDF]

open access: yesColloquium Mathematicum, 2021
We determine a particular class of Roter type warped product manifolds. We show that every manifold of that class admits a geodesic mapping onto a some Roter type warped product manifold. Moreover, both geodesically related manifolds are pseudosymmetric of constant type.

Infinite Product and Its Convergence in CAT(1) Spaces

open access: yesMathematics, 2023
In this paper, we study the convergence of infinite product of strongly quasi-nonexpansive mappings on geodesic spaces with curvature bounded above by one. Our main applications behind this study are to solve convex feasibility by alternating projections,

Canonical quasi-geodesic mappings of special pseudo-Riemannian spaces

open access: yesPracì Mìžnarodnogo Geometričnogo Centru, 2022
The present paper continues the study of quasi-geodesic mappings f:(Vn, gij, Fih) → (V'n,g'ij, Fih) of pseudo-Riemannian spaces Vn, V'n with a generalized-recurrent structure Fih of parabolic type.

(1,1)-geodesic maps into grassmann manifolds

open access: yesMathematische Zeitschrift, 1995
Let \(M\) be a Kähler manifold, \(D\) be the Levi-Civita connection extended complex-linearly to the complexification of the tangent bundle, \(N\) be a Riemannian manifold, and \(\varphi:M\to N\) be a smooth map. The Hessian \(Dd\varphi\) may be decomposed to \((2,0)\), \((1,1)\), \((0,2)\) parts. The map \(\varphi\) is called pluriharmonic if its \((1,

Gödel spacetime, planar geodesics and the Möbius map [PDF]

open access: yesGeneral Relativity and Gravitation, 2020
Timelike geodesics on a hyperplane orthogonal to the symmetry axis of the Gödel spacetime appear to be elliptic-like if standard coordinates naturally adapted to the cylindrical symmetry are used. The orbit can then be suitably described through an eccentricity-semi-latus rectum parametrization, familiar from the Newtonian dynamics of a two-body system.

Quantum lump dynamics on the two-sphere [PDF]

open access: yes, 2013
It is well known that the low-energy classical dynamics of solitons of Bogomol'nyi type is well approximated by geodesic motion in M_n, the moduli space of static n-solitons.

Convex (α, β)-Generalized Contraction and Its Applications in Matrix Equations

open access: yesAxioms, 2023
This paper investigates the existence and convergence of solutions for linear and nonlinear matrix equations. This study explores the potential of convex (α,β)-generalized contraction mappings in geodesic spaces, ensuring the existence of solutions for ...

Approximating Solutions of Optimization Problems via Fixed Point Techniques in Geodesic Spaces

open access: yesAxioms, 2022
The principal objective of this paper is to find the solution to a constrained minimization problem and the zero of the monotone operator in geodesic spaces. The basic tool in our study is a nonexpansive mapping.

Geodesic Generative Topographic Mapping

open access: yes, 2009
Nonlinear dimensionality reduction (NLDR) methods aim to provide a faithful low-dimensional representation of multivariate data. The manifold learning family of NLDR methods, in particular, do this by defining low-dimensional manifolds embedded in the observed data space.
