Curvature Bounds and Casorati Pinching for Submanifolds in Kähler Product Manifolds

open access: yesAxioms
In this paper, we establish sharp pinching inequalities that relate the generalized δ-Casorati curvatures to the normalized scalar curvature of submanifolds immersed in Kähler product manifolds endowed with a quarter-symmetric metric connection.

Some Pinching Results for Bi-Slant Submanifolds in S-Space Forms

open access: yesMathematics, 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 ...

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

open access: yesFilomat, 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 ...

Optimal inequalities for the normalizedδ-Casorati curvatures of submanifolds in Kenmotsu space forms

open access: yesAdvances in Geometry, 2017
AbstractIn this paper, we establish two sharp inequalities for the normalizedδ-Casorati curvatures of submanifolds in a Kenmotsu space form, tangent to the structure vector field of the ambient space.Moreover, we show that in both cases the equality at all points characterizes the totally geodesic submanifolds.

Bounds for generalized normalized δ-Casorati curvatures for submanifolds in Bochner Kaehler manifold

open access: yesFilomat, 2018
In this paper, we prove sharp inequalities between the normalized scalar curvature and the generalized normalized ?-Casorati curvatures for different submanifolds in Bochner Kaehler manifold. Moreover, We also characterize submanifolds on which the equalities hold.

An Optimal Inequality for Warped Product Pointwise Semi-Slant Submanifolds in Complex Space Forms

open access: yesAxioms
In this paper, we utilize advanced optimization techniques on Riemannian submanifolds to establish two distinct inequalities concerning the generalized normalized δ-Casorati curvatures of warped product pointwise semi-slant (WPPSS) submanifolds within ...

Recent developments in δ-Casorati curvature invariants

open access: yesTURKISH JOURNAL OF MATHEMATICS, 2021
One of the basic problems in submanifold theory is to find simple relationships between the main extrinsic and intrinsic invariants of a submanifold. In order to obtain viable solutions to this problem, the author introduced in the early 1990's new types of Riemannian invariants, known as \(\delta\)-invariants or Chen invariants.

Optimization on Submanifolds of $\delta$-Lorentzian trans-Sasakian Manifolds with Casorati Curvatures

open access: yesTamkang Journal of Mathematics, 2021
The present research article is concerned about a couple of optimal inequalities for submanifolds of $\delta$-Lorentzian trans-Sasakian manifolds endowed with semi-symmetric metric connection (briefly says $SSM$). Some examples of $\delta$-Lorentzian trans-Sasakiam manifolds are also discussed here. This paper ends with some open problems.
