Optimal inequalities for Riemannian maps and Riemannian submersions involving Casorati curvatures

open access: yesAnnali Di Matematica Pura Ed Applicata, 2020
The authors consider Riemannian maps and Riemannian submersions to obtain optimal inequalities in the theory of Riemannian maps, Riemannian submersions to space forms. The method is based on Casorati curvature. The important results in this work are described in the following sections: Riemannian maps to real space forms, Riemannian maps to complex ...

Inequalities for the Casorati Curvatures of Real Hypersurfaces in Some Grassmannians

open access: yesTaiwanese Journal of Mathematics, 2018
In this paper we obtain two types of optimal inequalities consisting of the normalized scalar curvature and the generalized normalized $δ$-Casorati curvatures for real hypersurfaces of complex two-plane Grassmannians and complex hyperbolic two-plane Grassmannians. We also find the conditions on which the equalities hold.

Inequalities for the Casorati curvatures of slant submanifolds in quaternionic space forms [PDF]

open access: yesJournal of Inequalities and Applications, 2014
Abstract In this paper we prove two sharp inequalities that relate the normalized scalar curvature with the Casorati curvature for a slant submanifold in a quaternionic space form. Moreover, we show that in both cases, the equality at all points characterizes the invariantly quasi-umbilical submanifolds.

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.

A pinching theorem for statistical manifolds with Casorati curvatures

open access: yesJournal of Nonlinear Science and Applications, 2017
Summary: With a pair of conjugate connections \(\overline{\nabla}\) and \(\overline{\nabla}^*\), we derive optimal Casorati inequalities with the normalized scalar curvature on submanifolds of a statistical manifold of constant curvature.

Optimal Inequalities for the Casorati Curvatures of Submanifolds in Generalized Space Forms Endowed with Semi-Symmetric Non-Metric Connections [PDF]

open access: yesSymmetry, 2016
In this paper, we prove some optimal inequalities involving the intrinsic scalar curvature and the extrinsic Casorati curvature of submanifolds in a generalized complex space form with a semi-symmetric non-metric connection and a generalized Sasakian space form with a semi-symmetric non-metric connection.
