Geodesic orbit and weakly symmetric spray manifolds [PDF]

Comptes Rendus. Mathématique
In this paper, we introduce the geodesic orbit and weakly symmetric properties in homogeneous spray geometry. When a homogeneous spray manifold is endowed with a reductive decomposition, we use the spray vector field to describe these properties, and ...

Weakly Z-symmetric manifolds [PDF]

Acta Mathematica Hungarica, 2011
We introduce a new kind of Riemannian manifold that includes weakly-, pseudo- and pseudo projective- Ricci symmetric manifolds. The manifold is defined through a generalization of the so called Z tensor; it is named "weakly Z symmetric" and denoted by (WZS)_n.

Hyper-Generalized Weakly Symmetric Para-Sasakian Manifolds and Their Geometric Properties

Қарағанды университетінің хабаршысы. Математика сериясы
This paper examines para-Sasakian manifolds that satisfy a hyper-generalized weakly symmetric curvature condition. The conditions under which such a manifold with a hyper-generalized weakly symmetric curvature condition satisfies the η-Einstein manifold

On Quasi-Conformally Flat Weakly Ricci Symmetric Manifolds [PDF]

Acta Mathematica Hungarica, 2007
The authors obtain certain properties of (pseudo-)Riemannian manifolds which are weakly Ricci symmetric and simultaneously quasi-conformally flat. The reader must be careful because the formulations of the theorems are not complete. For instance, Theorem 1 states that the Ricci tensor is of rank 1.

Weakly B-Symmetric Warped Product Manifolds With Applications

Axioms
This work presents a comprehensive study of weakly B-symmetric warped product manifolds (WBS)n, a natural extension of several classical curvature-restricted geometries including B-flat, B-parallel, and B-recurrent manifolds. We begin by formulating the fundamental properties of the B-tensor B(X,Y)=aS(X,Y)+brg(X,Y), where S is the Ricci tensor, r the ...
