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 ...

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 ...

Mabuchi Kähler solitons versus extremal Kähler metrics and beyond
Bulletin of the London Mathematical Society, Volume 57, Issue 3, Page 692-710, March 2025.Abstract Using the Yau–Tian–Donaldson type correspondence for v$v$‐solitons established by Han–Li, we show that a smooth complex n$n$‐dimensional Fano variety admits a Mabuchi soliton provided it admits an extremal Kähler metric whose scalar curvature is strictly less than 2(n+1)$2(n+1)$.

Fortschritte der Physik, Volume 73, Issue 1-2, February 2025.Abstract S. Gukov and C. Vafa proposed a characterization of rational N=(1,1)$N=(1,1)$ superconformal field theories (SCFTs) in 1+1$1+1$ dimensions with Ricci‐flat Kähler target spaces in terms of the Hodge structure of the target space, extending an earlier observation by G. Moore.

Ricci and scalar curvatures of submanifolds of a conformal Sasakian space form [PDF]
, 2016 summary:We introduce a conformal Sasakian manifold and we find the inequality involving Ricci curvature and the squared mean curvature for semi-invariant, almost semi-invariant, $\theta $-slant, invariant and anti-invariant submanifolds tangent to the ...

A Simple Proof of Chen–Ricci Inequality and Applications
GeometryIn the present paper, we give a simple proof of the Chen–Ricci inequality for submanifolds in Riemannian and Lorentzian space forms, respectively. Moreover, we extend the Chen–Ricci inequality to submanifolds in Lorentzian manifolds with a semi-symmetric non-metric connection.

Dynamical (In)Stability of Ricci-flat ALE metrics along the Ricci flow
, 2023 We study the stability and instability of ALE Ricci-flat metrics around which a Łojasiewicz inequality is satisfied for a variation of Perelman’s $$\lambda $$

Some generalizations of RADO'S inequality
, 2011 碩士在本文中，主要以系統化的方式整合文獻資料中與Rado不等式及Popoviciu不等式有相關的不等式。以更簡易的方法(如Jensen不等式和凸函數基本性質)去證明，最後再舉一些例子說明。In this article, mainly in the systematic way to with the Rado''s inequality and Popoviciu''s inequalities are related to inequality.
