D-Homothetic deformation of LP-Sasakian manifolds

Novi Sad Journal of Mathematics, 2015
Summary: The object of the present paper is to study a transformation called D-homothetic deformation of \(LP\)-Sasakian manifolds. Among others it is shown that in an \(LP\)-Sasakian manifold, the Ricci operator \(Q\) commutes with the structure tensor \(\varphi\).

Novel Theorems on Spacetime Admitting Pseudo‐W2 Curvature Tensor

Journal of Mathematics, Volume 2026, Issue 1, 2026.
This paper investigates spacetime manifolds admitting a pseudo‐W2 curvature tensor. We show that a pseudo‐W2 flat spacetime is an Einstein manifold and therefore has constant curvature. Moreover, when the manifold satisfies the Einstein field equations (EFE), with a cosmological constant, the associated energy–momentum tensor is covariantly constant ...

The Z‐Tensor on Almost Co‐Kählerian Manifolds Admitting Riemann Soliton Structure

Advances in Mathematical Physics, Volume 2024, Issue 1, 2024.
A Riemann soliton (RS) is a natural generalization of a Ricci soliton structure on pseudo‐Riemannian manifolds. This work aims at investigating almost co‐Kählerian manifolds (ACKM) 2n+1 whose metrics are Riemann solitons utilizing the properties of the Z‐tensor.

On Generalized Ricci-recurrent LP-sasakian Manifolds

Journal of Mathematics and Computer Science, 2015
The object of the present paper is to study a generalized Ricci-recurrent LP-Sasakian manifold. Here we show that the generalized Ricci-recurrent LP-Sasakian manifold admitting cyclic Ricci tensor is an Einstein manifold.

Anti-quasi-Sasakian manifolds [PDF]

, 2023
We introduce and study a special class of almost contact metric manifolds, which we call anti-quasi-Sasakian (aqS). Among the class of transversely Kahler almost contact metric manifolds (M, phi, xi, eta, g), quasi-Sasakian and anti-quasi-Sasakian ...
