A note on quasi-bi-slant submanifolds of Sasakian manifolds [PDF]
Arabian Journal of Mathematics, 2021 AbstractThe object of the present paper is to study the notion of quasi-bi-slant submanifolds of almost contact metric manifolds as a generalization of slant, semi-slant, hemi-slant, bi-slant, and quasi-hemi-slant submanifolds. We study and characterize quasi-bi-slant submanifolds of Sasakian manifolds and provide non-trivial examples to signify that ...

Types of Submanifolds in Metallic Riemannian Manifolds: A Short Survey
Mathematics, 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 ...

On pointwise quasi bi-slant submanifolds
Filomat, 2022 In this paper, we introduce a new class of submanifolds which are called pointwise quasi bi-slant submanifolds in almost Hermitian manifolds which extends quasi bi-slant, bi-slant, hemi-slant, semi-slant and slant submanifolds in a very natural way. Several basic results in this respect are proved in this paper.

Characterization of bi-slant submanifolds of paraSasakian manifold
Filomat, 2023 This paper aims to present work on bi-slant submanifolds of paraSasakian manifold. The study includes the definitions and some results on Type 1, Type 2, and Type 3 slant submanifolds. We define bi-slant submanifolds and derive characterization results with some illustrative examples.

Pointwise bi-slant submanifolds of a Kenmotsu manifold
Filomat, 2023 In the present paper, point wise bi-slant submanifolds are studied. Some geometrically important results are obtained in the second section and these findings are used in the third section to investigate bislant warped product submanifolds of a Kenmotsu manifold.

Improved Chen’s Inequalities for Submanifolds of Generalized Sasakian-Space-Forms
Axioms, 2022 In this article, we derive Chen’s inequalities involving Chen’s δ-invariant δM, Riemannian invariant δ(m1,⋯,mk), Ricci curvature, Riemannian invariant Θk(2≤k≤m), the scalar curvature and the squared of the mean curvature for submanifolds of generalized ...

Warped product pointwise bi-slant submanifolds of Kaehler manifolds [PDF]
Publicationes Mathematicae Debrecen, 2018 Warped product manifolds have been studied for a long period of time. In contrast, the study of warped product submanifolds from extrinsic point of view was initiated by the first author around the beginning of this century in [7, 8]. Since then the study of warped product submanifolds has been investigated by many geometers.

Warped product bi-slant submanifolds of cosymplectic manifolds
Filomat, 2017 In this paper, we study warped product bi-slant submanifolds of cosymplectic manifolds. It is shown that there is no proper warped product bi-slant submanifold other than pseudo-slant warped product. Finally, we give an example of warped product pseudo-slant submanifolds.
