Bounds for generalized normalized δ-Casorati curvatures for Bi-slant submanifolds in T-space forms

Filomat, 2018
In this paper, we prove the inequality between the generalized normalized ?-Casorati curvatures and the normalized scalar curvature for the bi-slant submanifolds in T-space forms and consider the equality case of the inequality. We also develop same results for semi-slant submanifolds, hemi-slant submanifolds, CR-submanifolds, slant ...

General improved Chen’s inequality for Warped product bi-slant submanifolds in Kenmotsu manifolds

Filomat
Recently, B.Y. Chen established a relationship for the squared norm of the second fundamental form (an extrinsic invariant) of warped product bi-slant submanifolds of Kenmotsu manifolds in terms of the warping function (an intrinsic invariant). In this paper, we study warped product bi-slant submanfolds of Kenmotsu manifolds.

Semi-slant and bi-slant submanifolds of almost contact metric 3-structure manifolds

TURKISH JOURNAL OF MATHEMATICS, 2013
In this paper we introduce the notions of semi-slant and bi-slant submanifolds of an almost contact 3-structure manifold. We give some examples and characterization theorems about these submanifolds. Moreover, the distributions of semi-slant submanifolds of 3-cosymplectic and 3-Sasakian manifolds are studied.

On some optimal inequalities for bi-slant submanifolds in metallic Riemannian space forms

In this paper, we derive some important optimal relationships for bi-slant submanifolds in metallic Riemannian product space forms enriching the understanding of their geometric properties and deepening the connection between intrinsic and extrinsic curvature invariants.

Quasi Bi-Slant Submanifolds of Kaehler Manifolds

International Electronic Journal of Geometry, 2022
In this paper, we introduce the new notion of quasi bi-slant submanifolds of almost Hermitian manifolds. Necessary and sufficient conditions for the integrability of distributions which are involved in the definition of such submanifolds of a Kaehler manifold are obtained.

Warped product bi-slant submanifolds of Kenmotsu manifold

Asian-European Journal of Mathematics, 2021
In this paper, we obtain several fundamental results of bi-slant submanifolds in a Kenmotsu manifold. Next, we give an example of such submanifolds. Later, we obtain some results of proper bi-slant submanifolds of a Kenmotsu manifold. Here, we show every warped product bi-slant submanifold of a Kenmotsu manifold to be a Riemannian product under some ...
