Semi-Conformally Flat Singly Warped Product Manifolds and Applications

open access: yesAxioms, 2023
This paper investigates singly warped product manifolds admitting semi-conformal curvature tensors. The form of the Riemann tensor and Ricci tensor of the base and fiber manifolds of a semi-conformally flat singly warped product manifold are provided. It

Riemann solitons on generalized weakly ω-symmetric α-cosymplectic manifolds [PDF]

open access: yesSurveys in Mathematics and its Applications, 2021
Generalized quasi-conformal curvature tensor (ω-tensor) has the flavor of conformal, conharmonic, concircular, projective, m-projective, W1-curvature, W2-curvature and W4-curvature tensors.

Second order chiral kinetic theory under gravity and antiparallel charge-energy flow

open access: yesJournal of High Energy Physics, 2021
We derive the chiral kinetic theory under the presence of a gravitational Riemann curvature. It is well-known that in the chiral kinetic theory there inevitably appears a redundant ambiguous vector corresponding to the choice of the Lorentz frame.

Conserved quantities for asymptotically AdS spacetimes in quadratic curvature gravity in terms of a rank-4 tensor [PDF]

open access: yesPhysical Review D, 2023
We investigate the conserved quantities associated to Killing isometries for asymptotically AdS spacetimes within the framework of quadratic-curvature gravity.

On the geometry of sub-Riemannian manifolds equipped with a canonical quarter-symmetric connection

open access: yesДифференциальная геометрия многообразий фигур, 2023
In this article, a sub-Riemannian manifold of contact type is under­stood as a Riemannian manifold equipped with a regular distribution of codimension-one and by a unit structure vector field orthogonal to this distribution. This vector field is called a

GENERELIZED CONHARMONIC CURVATURE TENSOR OF NEARLY KAHLER MANIFOLD

open access: yesTikrit Journal of Pure Science, 2018
In this paper we study the relationship between tensor algebraic curvature tensor, and General conharmonic curvature tensor of Nearly Kahler manifold, i. e. it has a classical symmetry properties of the Riemann carvatur tensor.

On equivalency of various geometric structures [PDF]

open access: yes, 2013
In the literature we see that after introducing a geometric structure by imposing some restrictions on Riemann-Christoffel curvature tensor, the same type structure given by imposing same restriction on other curvature tensors being studied.
