Semi‐Slant Warped Product Submanifolds of a Kenmotsu Manifold [PDF]

open access: yesMathematical Problems in Engineering, 2012
We study semi‐slant warped product submanifolds of a Kenmotsu manifold. We obtain a characterization for warped product submanifolds in terms of warping function and shape operator and finally proved an inequality for squared norm of second fundamental form.

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 ...

Characterizing Base in Warped Product Submanifolds of Complex Projective Spaces by Differential Equations

open access: yesMathematics, 2022
In this study, a link between the squared norm of the second fundamental form and the Laplacian of the warping function for a warped product pointwise semi-slant submanifold Mn in a complex projective space is presented.

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

open access: yesAdvances in Mathematical Physics, 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.

SEMI-SLANT SUBMANIFOLDS OF T-MANIFOLDS

open access: yesDemonstratio Mathematica, 2006
\(T\)--manifolds are a generalization of cosymplectic manifolds whose study was introduced by \textit{D. E. Blair} [J. Differ. Geom. 4, 155--167 (1970; Zbl 0202.20903)]. Semi-slant submanifolds are a generalization of CR-submanifolds. As indicated by the title of this paper, the authors investigate semi-slant submanifolds of a \(T\)--manifold.

Warped product semi-slant submanifolds in locally conformal Kaehler manifolds

open access: yesPracì 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.

Neutral Slant Submanifolds of a Para-Kähler Manifold

open access: yesAbstract and Applied Analysis, 2013
We define and study both neutral slant and semineutral slant submanifolds of an almost para-Hermitian manifold and, in particular, of a para-Kähler manifold. We give characterization theorems for neutral slant and semi-neutral slant submanifolds. We also

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 ...
