Hemi-slant submanifolds as warped products in a nearly Kaehler manifold

Mathematica Slovaca, 2017
AbstractThe present article is devoted to the study of conditions on a hemi-slant submanifold of a nearly Kaehler manifold under which the submanifold is a warped product submanifold.

On a submersion of generic submanifold of a nearly Kaehler manifold

International Journal of Geometric Methods in Modern Physics, 2022
The purpose of this paper is to study the submersions of a generic submanifold [Formula: see text] of a nearly Kaehler manifold [Formula: see text]. It is proved that the base space [Formula: see text] of such a submersion which is an almost Hermitian manifold, turns out to be nearly Kaehler. It is also shown under certain conditions that base [Formula:

Study of a Projective Ricci Semi-symmetric Nearly Kaehler Manifold

Asian Journal of Mathematics and Computer Research, 2023
We inaugurate a new curvature properties of projective curvature tensor in nearly Kaehler manifold. We defined projective Ricci semi-symmetric quasi-Einstein nearly Kaehler manifold, Projective Ricci semisymmetric generalised quasi-Einstein nearly Kaehler manifold and a Projective Ricci semi-symmetric pseudo generalised quasi-Einstein nearly Kaehler ...

Some results on normal GCR-lightlike submanifolds of indefinite nearly Kaehler manifolds

International Journal of Geometric Methods in Modern Physics, 2019
The purpose of this paper is to study normal [Formula: see text]-lightlike submanifolds of indefinite nearly Kaehler manifolds. We find some necessary and sufficient conditions for an isometrically immersed [Formula: see text]-lightlike submanifold of an indefinite nearly Kaehler manifold to be a normal [Formula: see text]-lightlike submanifold ...

Geometric classification of warped product submanifolds of nearly Kaehler manifolds with a slant fiber

International Journal of Geometric Methods in Modern Physics, 2019
There are two types of warped product pseudo-slant submanifolds, [Formula: see text] and [Formula: see text], in a nearly Kaehler manifold. We derive an optimization for an extrinsic invariant, the squared norm of second fundamental form, on a nontrivial warped product pseudo-slant submanifold [Formula: see text] in a nearly Kaehler manifold in terms ...

Some characterization theorems on GCR-lightlike warped product submanifolds of indefinite nearly Kaehler manifolds

International Journal of Geometric Methods in Modern Physics, 2020
It is shown that for a proper Generalized Cauchy–Riemann ([Formula: see text])-lightlike submanifold of an indefinite nearly Kaehler manifold such that [Formula: see text] defines a totally geodesic foliation in [Formula: see text], there does not exist any warped product [Formula: see text]-lightlike submanifold of the type [Formula: see text]. Then,

Conformal slant submersions from nearly Kaehler manifolds

International Journal of Geometric Methods in Modern Physics, 2021
We study slant submersions and conformal slant submersions from nearly Kaehler manifolds onto Riemannian manifolds and investigate conditions for such maps to be totally geodesic maps. We also obtain conditions for a slant submersion and a conformal slant submersion from a nearly Kaehler manifold onto a Riemannian manifold to be a harmonic map and a ...

Exposition of holomorphic Riemannian maps from nearly Kaehler manifolds

International Journal of Geometric Methods in Modern Physics, 2023
In this paper, we conduct a thorough investigation into holomorphic Riemannian maps from nearly Kaehler manifolds. We determine the necessary and sufficient conditions for these maps to be harmonic. In addition, we explore the scenario where the total manifold admits a Ricci soliton, analyze the properties of the holomorphic Riemannian maps in this ...
