Ricci curvature on warped product submanifolds in spheres with geometric applications

, 2019
The goal of this paper is to construct a fundamental theorem for the Ricci curvature inequality via partially minimal isometric warped product immersions into a m -dimensional unit sphere S m , involving the Laplacian of a well defined warping function ...

A Bibliometric Analysis of Four Decades of Shareholder Activism Research

Corporate Governance: An International Review, Volume 33, Issue 5, Page 946-984, September 2025.
ABSTRACT Research Questions/Issue In this bibliometric review of shareholder activism literature spanning 1983–2021, we pursue two objectives. Firstly, we investigate the degree of interdisciplinarity in the field, and second, we scrutinize publication trends, foundational knowledge, core topics, and emerging thematic trends, exploring the trajectory ...

Ricci Curvatures on Hypersurfaces of Almost Product-like Statistical Manifolds

Journal of Engineering Technology and Applied Sciences
Riemannian curvature invariants on hypersurfaces of an almost product-like manifold with constant curvature υ are computed. Various relationships involving sectional curvatures and Ricci curvatures have been obtained.

Sharp inequalities involving the Ricci curvature for Riemannian submersions

, 2017
Riemannian invariants play the most fundamental role in Riemannian geometry. These invariants determine the intrinsic and extrinsic characteristics of Riemannian manifolds which affect the behaviour of the Riemannian manifold in general form.

Ricci tensor of slant submanifolds in locally metallic product space forms

Filomat
In this paper, we investigate the Ricci tensor of slant submanifolds in locally metallic product space forms. We derive the Chen-Ricci inequality and discuss its equality case. We also provide several applications of our results.

Geometric Machine Learning

AI Magazine, Volume 46, Issue 1, Spring 2025.
Abstract A cornerstone of machine learning is the identification and exploitation of structure in high‐dimensional data. While classical approaches assume that data lies in a high‐dimensional Euclidean space, geometric machine learning methods are designed for non‐Euclidean data, including graphs, strings, and matrices, or data characterized by ...

Improved Chen inequality of Sasakian space forms with the Tanaka-Webster connection

, 2015
In this paper, we establish an improved Chen inequality between the pseudo-Ricci curvature and the square of pseudo mean curvature with respect to the Tanaka-Webster connection in Sasakian space forms, and also we study an improved Chen inequality for ...
