A Study on \(W_6\) and \(W_8\)-Curvature Tensors on \((LPK)_n\)-Manifold with a Quarter-Symmetric Metric Connection

International Journal of Analysis and Applications
The present paper deals with the study of W6 and W8-curvature tensors in an n-dimensional Lorentzian para-Kenmotsu manifold (briefly, (LPK)n-manifold) with a quarter-symmetric metric connection.

ON φ-CONHARMONICALLY FLAT LORENTZIAN PARA-KENMOTSU MANIFOLDS

The present paper deals with a class of Lorentzian almost paracontact metric manifolds namely Lorentzian para-Kenmotsu (briefly LP-Kenmotsu) manifolds. We study and have shown that a quasiconformally flat Lorentzian para-Kenmotsu manifold is locally isomorphic with a unit sphere Sn(1).

Some Properties of RICCI Solitons in LP-Kenmotsu Manifolds

Communications on Applied Nonlinear Analysis
Examining Ricci solitons in Lorentzian para-Kenmotsu manifolds is the goal of this paper. We have established that a symmetric parallel second-order covariant tensor in a Lorentzian para-Kenmotsu manifold is a constant multiple of the metric tensor.

ON CERTAIN CLASSES OF CONFORMALLY FLAT LORENTZIAN PARA-KENMOTSU MANIFOLDS

In this present paper, we classify and explore the geometrical significance of a class of Lorentzian almost paracontact metric manifolds namely Lorentzian para-Kenmotsu (briefly LP-Kenmotsu) manifolds whenever the manifolds are either conformally flat or conformally symmetric.

Invariant Submanifolds of a Lorentzian β-Kenmotsu Manifold

Amesia
In this paper we have investigated invariant submanifolds of Lorentzian β-Kenmotsu manifolds and obtained the necessary and sufficient conditions for total geodesic submanifolds of Lorentzian β-Kenmotsu manifolds.

On M-projective curvature tensor of Lorentzian β-Kenmotsu manifold

Mathematics and Computer Science
In this paper, we explore the characteristics of Lorentzian β - Kenmotsu manifolds admitting M - projective curvature tensor. We demonstrate that M - projectively flat and irrotational M - projective curvature tensor of Lorentzian β - Kenmotsu manifolds ...
