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.

Bi-Slant Submanifolds of Para Hermitian Manifolds [PDF]
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.

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.

On warped product bi-slant submanifolds of Kenmotsu manifolds [PDF]
Arab Journal of Mathematical Sciences, 2020 Chen (2001) initiated the study of CR-warped product submanifolds in Kaehler manifolds and established a general inequality between an intrinsic invariant (the warping function) and an extrinsic invariant (second fundamental form).In this paper, we establish a relationship for the squared norm of the second fundamental form (an extrinsic invariant) of ...

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.

International Journal of Mathematics and Mathematical Sciences, 2005 We establish inequalities between the Ricci curvature and the squared mean curvature, and also between the k-Ricci curvature and the scalar curvature for a slant, semi-slant, and bi-slant submanifold in a locally conformal almost cosymplectic manifold ...

Some Pinching Results for Bi-Slant Submanifolds in S-Space Forms
Mathematics, 2022 The objective of the present article is to prove two geometric inequalities for submanifolds in S-space forms. First, we establish inequalities for the generalized normalized δ-Casorati curvatures for bi-slant submanifolds in S-space forms and then we derive the generalized Wintgen inequality for Legendrian and bi-slant submanifolds in the same ambient

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.
