A Bibliometric Analysis of Four Decades of Shareholder Activism Research
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 ...

We study two-dimensional weighted N $$ \mathcal{N} $$ = (2) supersymmetric ℂℙ models with the goal of exploring their infrared (IR) limit. 𝕎ℂℙ(N, N ˜ $$ \tilde{N} $$ ) are simplified versions of world-sheet theories on non-Abelian strings in four ...

Dynamics of Lp multipliers on harmonic manifolds
Let $ X $ be a complete, simply connected harmonic manifold of purely exponential volume growth. This class contains all non-flat harmonic manifolds of nonpositive curvature, and in particular all known examples of non-compact harmonic manifolds except ...

The Economic Consequences of Social Unrest: Evidence from Initial Public Offerings
ABSTRACT Prior research attributes negative stock market performance following episodes of social unrest to elevated uncertainty. However, social unrest does not solely increase uncertainty but separately acts to decrease investor sentiment. To determine which effect dominates, we study initial public offering (IPO) underpricing, which responds ...

Levi-Civita Ricci-flat metrics on compact complex manifolds [PDF]
In this paper, we study the geometry of compact complex manifolds with Levi-Civita Ricci-flat metrics and prove that compact complex surfaces admitting Levi-Civita Ricci-flat metrics are Kahler Calabi-Yau surfaces or Hopf surfaces.

Removing scalar curvature assumption for Ricci flow smoothing
Abstract In recent work of Chan–Huang–Lee, it is shown that if a manifold enjoys uniform bounds on (a) the negative part of the scalar curvature, (b) the local entropy, and (c) volume ratios up to a fixed scale, then there exists a Ricci flow for some definite time with estimates on the solution assuming that the local curvature concentration is small ...

Ricci-flat manifolds of generalized ALG asymptotics
In complex dimensions $\geq 3$, we provide a geometric existence for generalized ALG complete non-compact Ricci flat Kähler manifolds with Schwartz decay i.e. metric decay in any polynomial rate to an ALG model $\mathbb{C}\times Y$ modulo finite cyclic group action, where $Y$ is Calabi-Yau.

The interannual stability of the carabid biomass in agricultural fields can be maximised by supporting the in‐field mean alpha‐richness that reduces their temporal beta‐diversity. Increasing crop phenology diversity at the landscape level also stabilises carabid biomass over time. Abstract While the temporal stability of plant communities has been well

On Pseudo Cyclic Ricci Symmetric Manifolds
: The object of the present paper is to study concircularly symmetric (PCRS)n, concircularly recurrent (PCRS)n, decomposable (PCRS)n. Among others it is shown that in a decomposable (PCRS)n one of the decompositions is Ricci flat and the other ...
