Cr-submanifolds of a lorentzian para-sasakian manifold with a semi-symmetric metric connection

, 2010
We study CR-submanifolds of a Lorentzian para-Sasakian manifold endowed with a semi-symmetric metric connection. Moreover, we obtain integrability conditions of the distributions on CR-submanifolds.

Studies on Sasakian, Lorentzian para (LP)-Sasakian manifold and other related manifolds

, 2007
Ph.d ThesisThe study of tensors in differentiable manifolds that vary in structure have attracted many researchers. In this thesis out of many newly defined tensors W2 -curvature tensor and W4 -curvature tensor have been studied in Sasaki an, Para ...

Pointwise slant semi-riemannian submersions from lorentzian para-sasakian manifolds

, 2019
The purpose of this paper is to study pointwise slant semi-Riemannian submersions from Lorentzian paraSasakian manifolds. Several basic results in this point of view are proven in this paper. Definition 1. Let F be a semi-Riemannian submersion from a Lorentzian (para) contact manifold (M, ?, ?, ?, gM) of dimension (2m+ 1) onto (N, gN ) be a Lorentzian ...

Second Order Parallel Tensors on LP-Sasakian Manifolds with a coefficient α

, 2017
In 1926, Levy [3] had proved that a second order symmetric parallel nonsingular tensor on a space of constant curvature is a constant multiple of the metric tensor.

Non-existence of CR-warped Product Submanifolds of Nearly Lorentzian Para-Sasakian Manifolds

Turkish Journal of Mathematics and Computer Science
We introduce the definition of the nearly Lorentzian para-Sasakian condition, and we show the non-existence of proper CR-warped product submanifolds in a nearly Lorentzian para-Sasakian manifold.

A Note On Smale Manifolds And Lorentzian Sasaki-Einstein Geometry

, 2016
In this note, we construct new examples of Lorentzian Sasaki-Einstein (LSE) metrics on Smale manifolds M. It has already been established by the author that such metrics exist on the so-called torsion free Smale manifolds, i.e.

Tachibana operator Applied to 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.
