Geometry of Harmonic Nearly Trans-Sasakian Manifolds [PDF]

Axioms, 2023
This paper considers a class of nearly trans-Sasakian manifolds. The local structure of nearly trans-Sasakian structures with a closed contact form and a closed Lee form is obtained.

η-Ricci Solitons on Sasakian 3-Manifolds [PDF]

Annals of the West University of Timisoara: Mathematics and Computer Science, 2017
In this paper we study η-Ricci solitons on Sasakian 3-manifolds. Among others we prove that an η-Ricci soliton on a Sasakian 3-manifold is an η-Einstien manifold.

Slant Riemannian submersions from Sasakian manifolds [PDF]

Arab Journal of Mathematical Sciences, 2016
We introduce and characterize slant Riemannian submersions from Sasakian manifolds onto Riemannian manifolds. We survey main results of slant Riemannian submersions defined on Sasakian manifolds.

Some New Results on Trans-Sasakian Manifolds [PDF]

Journal of Mathematics, 2022
In this paper, we classify trans-Sasakian manifolds which are realized as real hypersurfaces in a complex space form. We also investigate trans-Sasakian manifolds whose Reeb vector fields are harmonic-Killing.

Nearly Sasakian Manifolds of Constant Type [PDF]

Axioms, 2022
The article deals with nearly Sasakian manifolds of a constant type. It is proved that the almost Hermitian structure induced on the integral manifolds of the maximum dimension of the first fundamental distribution of the nearly Sasakian manifold is a ...

A Note on Nearly Sasakian Manifolds [PDF]

Mathematics, 2023
A class of nearly Sasakian manifolds is considered in this paper. We discuss the geometric effects of some symmetries on such manifolds and show, under a certain condition, that the class of Ricci semi-symmetric nearly Sasakian manifolds is a subclass of

Warped Product Submanifolds of LP-Sasakian Manifolds [PDF]

Discrete Dynamics in Nature and Society, 2012
We study of warped product submanifolds, especially warped product hemi-slant submanifolds of LP-Sasakian manifolds. We obtain the results on the nonexistance or existence of warped product hemi-slant submanifolds and give some examples of LP-Sasakian ...

$n$-Sasakian manifolds [PDF]

Tohoku Mathematical Journal, 2008
Let \(\pi: M\to B\) be a Riemannian orbifold submersion with totally geodesic leaves such that for any \(V\in T_x F\) (\(F\) is the leaf) and any \(X,Y\in T_x M\) it holds that \(R(X,Y)V=\langle Y,V\rangle X-\langle X,V\rangle Y\) for each \(x\in M\). Then \(M\) is said to be \(n\)-Sasakian, where \(n=\dim F\). This is a generalization of the notion of

Generalized Z-Solitons on LP-Sasakian Manifolds With the General Connection

Journal of Mathematics
This work focuses on LP-Sasakian manifolds endowed with generalized Z-solitons constructed with respect to an arbitrary affine connection. To conclude, we provide an explicit and nontrivial example in the four-dimensional case, thereby establishing the ...
