A note on pseudoparallel submanifolds of Lorentzian para-Kenmotsu manifolds

, 2023
In this article, pseudoparallel submanifolds for Lorentzian para-Kenmotsu manifolds are inves-tigated. The Lorentzian para-Kenmotsu manifold is considered on the W1 −curvature tensor.

Ricci solitons in Lorentzian α-Sasakian manifolds

, 2012
We study Ricci solitons in Lorentzian α-Sasakian manifolds. It is shown that a symmetric parallel second order covariant tensor in a Lorentzian α-Sasakian manifold is a constant multiple of the metric tensor.

ALMOST CONFORMAL RICCI SOLITONS ON LP-SASAKIAN MANIFOLDS [PDF]

The object of the present paper is to classify almost conformal Ricci solitons on Lorentzian para-Sasakian manifolds. In this paper, we prove that such manifolds with infinitesimal contact vector field V is η-Einstein and the scalar curvature of the ...

ON QUASI BI-SLANT RIEMANNIAN MAPS FROM LORENTZIAN PARA SASAKIAN MANIFOLDS

Journal of the Indonesian Mathematical Society
We first introduce quasi bi-slant Riemannian maps and study such Riemannian maps from Lorentzian para Sasakian manifolds into Riemannian manifolds. We give necessary and sufficient conditions for the integrability of the distributions which are involved in the definition of the quasi bi-slant Riemannian map and investigate their leaves.

Ricci Solitons in (ε,δ)-Trans-Sasakian Manifolds

, 2017
We study Ricci solitons in (ε,δ)-trans-Sasakian manifolds. It is shown that a symmetric parallel second order covariant tensor in a (ε,δ)-trans-Sasakian manifold is a constant multiple of the metric tensor.

Warped product CR-submanifolds in Lorentzian para Sasakian manifolds

, 2010
Summary: Many research articles have recently appeared exploring existence or non existence of warped product submanifolds in known spaces (cf. \textit{B. Y. Chen} [Monatsh. Math. 133, No.3, 177--195 (2001; Zbl 0996.53044)]; \textit{I. Hasegawa} and \textit{I. Mihai} [Geom. Dedicata 102, 143--150 (2003; Zbl 1066.53103)]; \textit{M. I.

Applications of the Tachibana operator on invariant submanifolds of Lorentzian Trans-Sasakian manifolds

In the present paper, Tachibana operatory is applied to an invariant submanifold of a lorentzian trans-Sasakian manifold by means of through various tensors and the results obtained are discussed in terms of geometry.
