Some properties of concircular, conharmonic and projective curvature tensors on 4-dimensional lorentzian and riemannian spaces

, 2022
We investigate some features of concircular, conharmonic, and projective curvature tensors on 4-dimensional Lorentzian and Riemannian spaces. Using the known holonomy algebras for the metric signatures (+, +, +, −) and (+, +, +, +), we prove some theorems on these tensor elds.

Traceless component of the conformal curvature tensor in Kähler manifold [PDF]

Czechoslovak Mathematical Journal, 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.

On the \(D\)-concircular curvature tensor of a generalized Sasakian-space-form

2021
Summary: The object of this paper is to study of \(D\)-concircular curvature tensor on generalized Sasakian-space-forms. Actually we consider generalized Sasakian-space-forms when it is, respectively: \(D\)-concircularly flat; \(D\)-concircular-pseudosymmetric; \(D\)-concircularly Ricci-semisymmetric; \(D\)-concircularly symmetric; \(V(xi,X) .R = 0 ...

Concircular curvature tensor on \(K\)-contact manifolds

2013
Summary: The object of the present paper is to study \(\xi\)-concircularly flat, \(\phi\)-concircularly flat and concircularly semisymmetric \(K\)-contact manifolds. Beside these we also study \(K\)-contact manifolds satisfying \(Z(\xi,X). S = 0\).
