Pointwise hemi-slant warped product submanifolds in nearly Kaehler manifolds

Analele ştiinţifice ale Universităţii "Ovidius" Constanţa. Seria Matematică
Abstract In this paper, we introduce the notion of pointwise hemi-slant sub-manifolds of nearly Kaehler manifolds. Further, we study their warped products and prove the necessary and sufficient condition that a point-wise hemi-slant submanifold to be a warped product manifold. Also, we establish a sharp inequality

Optimal inequalities involving Casorati curvatures for Riemannian maps to nearly Kaehler manifolds

Journal of Inequalities and Applications
We establish a general inequality and optimal inequalities involving the normalized Casorati curvatures and the generalized normalized Casorati curvatures within the horizontal space of a Riemannian map from a Riemannian manifold to a nearly Kaehler ...

Geometric Mechanics on Warped Product Semi‐Slant Submanifold of Generalized Complex Space Forms

Advances in Mathematical Physics, Volume 2021, Issue 1, 2021., 2021
In this study, we develop a general inequality for warped product semi‐slant submanifolds of type Mn=NTn1×fNϑn2 in a nearly Kaehler manifold and generalized complex space forms using the Gauss equation instead of the Codazzi equation. There are several applications that can be developed from this.

Warped product semi-slant submanifolds in locally conformal Kaehler manifolds II

Pracì Mìžnarodnogo Geometričnogo Centru, 2019
In 1994 N.~Papaghiuc introduced the notion of semi-slant submanifold in a Hermitian manifold which is a generalization of $CR$- and slant-submanifolds, \cite{MR0353212}, \cite{MR760392}.

Warped product semi-slant submanifolds in locally conformal Kaehler manifolds

Pracì Mìžnarodnogo Geometričnogo Centru, 2017
In 1994, in [13], N. Papaghiuc introduced the notion of semi-slant submanifold in a Hermitian manifold which is a generalization of CR- and slant-submanifolds. In particular, he considered this submanifold in Kaehlerian manifolds, [13]. Then, in 2007, V.

Anti-invariant Riemannian submersions from nearly Kaehler manifolds

Filomat, 2013
We extend the notion of anti-invariant and Langrangian Riemannian submersion to the case when the total manifold is nearly Kaehler. We obtain the integrability conditions for the horizontal distribution while it is noted that the vertical distribution is always integrable.

Warped product pointwise semi-slant submanifolds of nearly Kaehler manifolds

Filomat
In this paper, we study warped pointwise semi-slant submanifolds of nearly Kaehler manifolds. We prove that there do not exist non-trivial warped product pointwise semi-slant submanifolds of the form N?? f NT in a nearly Kaehler manifold ?M but the geometry of warped products by reversing these two factors is similar to the case of general ...

Magnetic exchange interactions in binuclear and tetranuclear iron(III) complexes described by spin-flip DFT and Heisenberg effective Hamiltonians. [PDF]

J Comput Chem, 2023
Exchange interactions in polynuclear Fe (III) compounds are derived from ab initio calculations based on a single spin‐flip (1SF) approach. Abstract Low‐energy spectra of single‐molecule magnets (SMMs) are often described by Heisenberg Hamiltonians.

Hemi-slant submanifolds of nearly Kaehler manifolds

Gulf Journal of Mathematics, 2016
In the present paper, we study the hemi-slant submanifolds of nearly Kaehler manifolds. We study the integrability of distributions involved in the definition of hemi-slant submanifolds. Some results are worked out on totally umbilical hemi-slant submanifolds. We study the cohomology class for hemi-slant submanifolds of nearly Kaehler manifolds.

Sequential warped product submanifolds in nearly Kaehler manifolds

Filomat, 2023
A new class of warped product manifolds which is known as sequential warped product manifolds have been defined in [15] and studied in detail in [9]. This article is dedicated to study sequential warped product submanifolds having factors holomorphic, totally real and pointwise slant submanifolds of nearly Kaehler manifolds.
