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.

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 ...

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

Conformal-twisted product semi-slant submanifolds in globally conformal Kaehler manifolds

open access: yesHacettepe Journal of Mathematics and Statistics, 2021
We introduce the notion of conformal-twisted product submanifolds of the form $_fM^{T}\times_{b}M^{\theta}$ and $_fM^{\theta}\times_{b}M^{T}$, where $M^T$ is a holomorphic submanifold and $M^\theta$ is a proper slant submanifold of $M$ in a globally conformal Kaehler manifold and $f$ and $b$ are conformal factor and twisting function, respectively. We

Pointwise almost h-semi-slant submanifolds [PDF]

open access: yesInternational Journal of Mathematics, 2015
We introduce the notions of pointwise almost h-slant submanifolds and pointwise almost h-semi-slant submanifolds as a generalization of slant submanifolds, pointwise slant submanifolds, semi-slant submanifolds, and pointwise semi-slant submanifolds.

A note on pointwise semi-slant submanifold of para-Cosymplectic manifolds

open access: yesFilomat, 2022
This article covers the geometric study of pointwise slant and pointwise semi-slant submanifolds of a para-Cosymplectic manifold M? 2m+1 with the semi-Riemannian metric. We give an advanced definition of these type of submanifolds for the spacelike and timelike vector fields.

Ricci Curvature Inequalities for Skew CR-Warped Product Submanifolds in Complex Space Forms

open access: yesMathematics, 2020
The fundamental goal of this study was to achieve the Ricci curvature inequalities for a skew CR-warped product (SCR W-P) submanifold isometrically immersed in a complex space form (CSF) in the expressions of the squared norm of mean curvature vector and

Semi-slant submanifolds in a locally conformal Kaehler space form

open access: yesHacettepe Journal of Mathematics and Statistics, 2023
In this paper, we consider semi-slant submanifolds in a locally conformal Kaehler manifold and a locally conformal Kaehler space form. We give inequalities for the length of the second fundamental form and the mean curvature and, using Gauss and Codazzi equations, we get many useful results in locally conformal Kaehler space form.
