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

Дифференциальная 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

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

Surveys 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.

TRACELESS COMPONENT OF THE CONFORMAL CURVATURE TENSOR IN KÄHLER MANIFOLD [PDF]

, 2006
We investigate the traceless component of the conformal curvature tensor de-fined by (2.1) in Kähler manifolds of dimension> 4, and show that the traceless component is invariant under concircular change.

Some Curvature Conditions on a Para-Sasakian Manifold with Canonical Paracontact Connection

International Journal of Mathematics and Mathematical Sciences, 2012
We study canonical paracontact connection on a para-Sasakian manifold. We prove that a Ricci-flat para-Sasakian manifold with respect to canonical paracontact connection is an η-Einstein manifold.

On the Geometry of the Riemannian Curvature Tensor of Nearly Trans-Sasakian Manifolds

Axioms, 2023
This paper presents the results of fundamental research into the geometry of the Riemannian curvature tensor of nearly trans-Sasakian manifolds. The components of the Riemannian curvature tensor on the space of the associated G-structure are counted, and

A new curvature-like tensor in an almost contact Riemannian manifold

Pracì Mìžnarodnogo Geometričnogo Centru, 2016
In a M. Prvanović’s paper [5], we can find a new curvature-like tensor in an almost Hermitian manifold.In this paper, we define a new curvature-like tensor, named contact holomorphic Riemannian, briefly (CHR), curvature tensor in an almost ...

Invariants over Curvature Tensor Fields [PDF]

, 1998
In this paper, we present constructions of higher-order polynomialO(n)-invariants over curvature tensor fields. These invariants are higher-order analogues of the scalar curvature. Our methods are based on certain replicative properties of theO(n)-module

A (CHR)3-flat trans-Sasakian manifold

Pracì Mìžnarodnogo Geometričnogo Centru, 2019
In [4] M. Prvanovic considered several curvaturelike tensors defined for Hermitian manifolds. Developing her ideas in [3], we defined in an almost contact Riemannian manifold another new curvaturelike tensor field, which is called a contact ...
