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

Geometrical Properties of the Pseudonull Hypersurfaces in Semi-Euclidean 4-Space
Mathematics, 2021 In this paper, we focus on some geometrical properties of the partially null slant helices in semi-Euclidean 4-space. By structuring suitable height functions, we obtain the singularity types of the pseudonull hypersurfaces, which are generated by the ...

SEMI-SLANT SUBMANIFOLDS OF T-MANIFOLDS
Demonstratio 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.

Semi-slant Riemannian maps into almost Hermitian manifolds [PDF]
Czechoslovak Mathematical Journal, 2014 The present paper introduces, characterizes and provides several examples of semi-slant Riemannian maps (SSRM) from Riemannian manifolds to almost Hermitian manifolds. This class of maps contains semi-slant immersions (therefore holomorphic immersions, totally real immersions, slant immersions), invariant Riemannian maps, anti-invariant Riemannian maps,

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.

Neutral Slant Submanifolds of a Para-Kähler Manifold
Abstract 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

Bi-Slant Submanifolds of Para Hermitian Manifolds
Mathematics, 2019 In this paper, we introduce the notion of bi-slant submanifolds of a para Hermitian manifold. They naturally englobe CR, semi-slant, and hemi-slant submanifolds. We study their first properties and present a whole gallery of examples.

An Optimal Inequality for the Normal Scalar Curvature in Metallic Riemannian Space Forms
Mathematics, 2023 In this paper, we prove the DDVV conjecture for a slant submanifold in metallic Riemannian space forms with the semi-symmetric metric connection. The equality case of the derived inequality is discussed, and some special cases of the inequality are given.

Inequalities for the Class of Warped Product Submanifold of Para-Cosymplectic Manifolds
Advances in Mathematical Physics, 2022 The aim of this paper is to study the warped product pointwise semislant submanifolds in the para-cosymplectic manifold with the semi-Riemannian metric.
