TRANS-PARA-SASAKIAN MANIFOLDS SATISFYING CERTAIN CURVATURE CONDITIONS

open access: yes
The main aim of this paper is to study (2n+1)-dimensional trans-para-Sasakian manifolds satisfying the curvature conditions P.Q = 0, Q.P = 0, P.R = 0, where P is the projective curvature tensor, Q is the Ricci operator, and R is the Riemannian curvature ...

On Quasi-Sasakian Manifolds

open access: yes, 2019
In this paper we study three-dimensional quasi-Sasakian manifolds admitting the Schoutenvan Kampen connection. Also, we study D-homothetic deformations on three-dimensional quasi-Sasakian manifolds admitting Schouten-van connection and projectively flat ...

Anti-invariant and Lagrangian submersions from trans-Sasakian manifolds

open access: yes, 2020
We study anti-invariant and Lagrangian submersions from trans-Sasakian manifolds onto Riemannian manifolds. We prove that the horizontal distributions of such submersions are not integrable and their fibers are not totally geodesic. Consequently, they

On slant curves in trans-sasakian manifolds

open access: yes, 2014
We find the characterizations of the curvatures of slant curves in trans-Sasakian manifolds with C-parallel and C-proper mean curvature vector field in the tangent and normal bundles.

Generalized -Einstein 3-dimensional trans-Sasakian manifold

open access: yes, 2020
. In the present note we have introduced a new concept called generalized -Einstein manifold in a 3-dimensional trans-Sasakian manifold and have given some preliminary ideas about the same.

WARPED PRODUCT CONTACT CR-SUBMANIFOLDS OF TRANS-SASAKIAN MANIFOLDS

open access: yes, 2014
B.Y. Chen [4] showed that there exists no proper warped CRsubmanifolds N ⊥ ×f NT of a Kaehler manifold and obtained many results on CR-warped products NT ×f N⊥. Contact CR-warped product submanifolds in Sasakian manifold were studied by I. Hasegawa and I.

On weakly concircular ï¦- symmetric of -trans sasakian manifolds

open access: yes, 2012
The purpose of this paper is to introduce a new concept such as weakly concircular ï¦- symmetric -Trans-Sasakian manifold, and study its properties. A series of corollaries from the theorems are also obtained and a concrete example for the existence ...
