Lp-cohomology of negatively curved manifolds [PDF]
, 2004 We compute the $L^p$-cohomology spaces of some negatively curved manifolds. We deal with two cases: manifolds with finite volume and sufficiently pinched negative curvature, and conformally compact manifolds.

Ambient connections realising conformal Tractor holonomy
, 2006 For a conformal manifold we introduce the notion of an ambient connection, an affine connection on an ambient manifold of the conformal manifold, possibly with torsion, and with conditions relating it to the conformal structure.

Journal of High Energy Physics, 2020 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
Electronic Research Archive, 2022 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 ...

Liouville Theorems for holomorphic maps on pseudo-Hermitian manifolds [PDF]
arXiv, 2021 We prove some Liouville type results for generalized holomorphic maps in three classes: maps from pseudo-Hermitian manifolds to almost Hermitian manifolds, maps from almost Hermitian manifolds to pseudo-Hermitian manifolds and maps from pseudo-Hermitian manifolds to pseudo-Hermitian manifolds, assuming that the domains are compact.

Construction of Ricci-type connections by reduction and induction [PDF]
, 2003 Given the Euclidean space $\R^{2n+2}$ endowed with a constant symplectic structure and the standard flat connection, and given a polynomial of degree 2 on that space, Baguis and Cahen have defined a reduction procedure which yields a symplectic manifold ...

A Bibliometric Analysis of Four Decades of Shareholder Activism Research
Corporate Governance: An International Review, EarlyView.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 ...

The extended quasi-Einstein manifolds with generalised Ricci solitons [PDF]
arXiv, 2022 As a generalization of Einstein manifolds, the nearly quasi-Einstein manifolds and pseudo quasi-Einstein manifolds are both interesting and useful in studying the general relativity. In this paper, we study the extended quasi-Einstein manifolds which derive from pseudo quasi-Einstein manifolds.

Levi-Civita Ricci-flat metrics on compact complex manifolds [PDF]
The Journal of Geometric Analysis, 2019 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.

The Economic Consequences of Social Unrest: Evidence from Initial Public Offerings
European Financial Management, EarlyView.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 ...
