Certain investigations of sequential warped product submanifolds on cosymplectic manifolds

open access: yesJournal of Inequalities and Applications, 2023
In a special class of almost contact metric manifolds known as cosymplectic manifolds, the current study aims to establish the existence result and a few inequalities for sequential warped product submanifolds.

A General Inequality for CR‐Warped Products in Generalized Sasakian Space Form and Its Applications

open access: yesAdvances in Mathematical Physics, Volume 2021, Issue 1, 2021., 2021
In the present paper, by considering the Gauss equation in place of the Codazzi equation, we derive new optimal inequality for the second fundamental form of CR‐warped product submanifolds into a generalized Sasakian space form. Moreover, the inequality generalizes some inequalities for various ambient space forms.

Characterization of GCR-lightlike warped product of indefinite Sasakian manifolds

open access: yesArab Journal of Mathematical Sciences, 2014
In this paper we prove that there do not exist warped product GCR-lightlike submanifolds in the form M = N⊥ × λNT such that N⊥ is an anti-invariant submanifold tangent to V and NT an invariant submanifold of M‾, other than GCR-lightlike product in an ...

Vanishing Homology of Warped Product Submanifolds in Complex Space Forms and Applications

open access: yesMathematics, 2022
In this paper, we prove the nonexistence of stable integral currents in compact oriented warped product pointwise semi-slant submanifold Mn of a complex space form M˜(4ϵ) under extrinsic conditions which involve the Laplacian, the squared norm gradient ...

Analysis of Obata’s Differential Equations on Pointwise Semislant Warped Product Submanifolds of Complex Space Forms via Ricci Curvature

open access: yesMathematical Problems in Engineering, Volume 2021, Issue 1, 2021., 2021
The present paper studies the applications of Obata’s differential equations on the Ricci curvature of the pointwise semislant warped product submanifolds. More precisely, by analyzing Obata’s differential equations on pointwise semislant warped product submanifolds, we demonstrate that, under certain conditions, the base of these submanifolds is ...

Study of Differential Equations on Warped Product Semi‐Invariant Submanifolds of the Generalized Sasakian Space Forms

open access: yesAdvances in Mathematical Physics, Volume 2021, Issue 1, 2021., 2021
The purpose of the present paper is to study the applications of Ricci curvature inequalities of warped product semi‐invariant product submanifolds in terms of some differential equations. More precisely, by analyzing Bochner’s formula on these inequalities, we demonstrate that, under certain conditions, the base of these submanifolds is isometric to ...

Classification of Warped Product Submanifolds in Kenmotsu Space Forms Admitting Gradient Ricci Solitons

open access: yesMathematics, 2019
The purpose of this article is to obtain geometric conditions in terms of gradient Ricci curvature, both necessary and sufficient, for a warped product semi-slant in a Kenmotsu space form, to be either CR-warped product or simply a Riemannian product ...

On differential equations classifying a warped product submanifold of cosymplectic space forms

open access: yesJournal of Inequalities and Applications, 2021
In the present paper, we extend the study of (Ali et al. in J. Inequal. Appl. 2020:241, 2020) by using differential equations (García-Río et al. in J. Differ. Equ. 194(2):287–299, 2003; Pigola et al. in Math. Z. 268:777–790, 2011; Tanno in J. Math.

Types of Submanifolds in Metallic Riemannian Manifolds: A Short Survey

open access: yesMathematics, 2021
We provide a brief survey on the properties of submanifolds in metallic Riemannian manifolds. We focus on slant, semi-slant and hemi-slant submanifolds in metallic Riemannian manifolds and, in particular, on invariant, anti-invariant and semi-invariant ...
