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

Axioms, 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.

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

Colloquium 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.

A Common Fixed Point Theorem for Vicinal Mappings on Geodesic Spaces [PDF]

Axioms
In 2024, Kimura proposed the modified shrinking method without assuming the existence of a common fixed point for a family of nonexpansive mappings defined on a complete geodesic space with a nonpositive upper curvature bound.

Geometry-Aware Enhanced 6DRepNet for Single-RGB Head Pose Estimation. [PDF]

Sensors (Basel)
Head pose estimation is a fundamental task in facial analysis and behavior understanding. To address the limitations of 6DRepNet in single-RGB scenarios, particularly in high-level spatial discriminative region modeling, global feature-to-6D rotation ...

On geodesic mappings of threesymmetric spaces

Proceedings of the International Geometry Center
The paper is devoted to the study of properties of pseudo-Riemannian spaces admitting nontrivial geodesic mappings. Necessary and sufficient conditions are found for A-threesymmetric spaces to admit nontrivial geodesic mappings. The research is carried out locally, in tensor form without restrictions to the sign of the metric tensor and the signature ...

Some Remarks on Geodesic and Curvature Preserving Mappings

Zeitschrift für Analysis und ihre Anwendungen, 1997
We ask for the converse of Gauss’ theorema egregium. Because in general isocurved manifolds are not isometric we ask stronger for isocurved, geodesic equivalent manifolds. For these we give a local criterion from which there follows that two-dimensional manifolds \overline{\mathcal M}^2
