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 ...

A Generalization of K. T. Chen's Invariants for Paths Under Transformation Groups [PDF]
Transactions of the American Mathematical Society, 1962 In a series of papers [1; 2; 3; 4], K. T. Chen introduced and studied certain infinite series of numbers associated with paths in Euclidean n-space. These numbers were invariants under translations, and in [4] he proved that they uniquely characterize paths under translations.

Tsukuba Journal of Mathematics, 2001 If a Riemannian manifold \(M\) can be minimally and isometrically immersed into a Euclidean space then, by the Gauss equation, the Ricci curvature of \(M\) is nonpositive. The author shows by an example that the curvature condition is not sufficient, i.e.

Geometric Inequalities for a Submanifold Equipped with Distributions
Mathematics, 2022 The article introduces invariants of a Riemannian manifold related to the mutual curvature of several pairwise orthogonal subspaces of a tangent bundle. In the case of one-dimensional subspaces, this curvature is equal to half the scalar curvature of the

A New Algebraic Inequality and Some Applications in Submanifold Theory
Mathematics, 2021 We give a simple proof of the Chen inequality involving the Chen invariant δ(k) of submanifolds in Riemannian space forms. We derive Chen’s first inequality and the Chen–Ricci inequality.

Chen invariants for Riemannian submersions and their applications
Communications Faculty Of Science University of Ankara Series A1Mathematics and Statistics, 2022 In this paper, an optimal inequality involving the delta curvature is exposed. With the help of this inequality some characterizations about the vertical motion and the horizontal divergence are obtained.
