The Architecture of Consolidation: Nests of Corporate Control in the Agrochemical Network

Journal of Agrarian Change, Volume 26, Issue 4, October 2026.
ABSTRACT Research on agricultural consolidation tends to equate corporate control with the dominance of a few large firms. We take an alternative approach that examines control through the explosive growth of legally distinct firms that fragment accountability. Using a new global dataset of 6982 entities linked to BASF, Bayer, Corteva, Dow, DuPont, FMC,

Political Ideology and Green Innovation: Cross‐National Evidence and Asia‐Pacific Policy Implications

Asia &the Pacific Policy Studies, Volume 13, Issue 3, September 2026.
ABSTRACT This article examines the relationship between political ideology and green innovation using an unbalanced panel of 131 countries from 1996 to 2020. Green innovation is proxied by environmental management patents, while political ideology is captured through the orientations of the chief executiveʼs party and the largest government party.

Ricci curvature of real hypersurfaces in complex hyperbolic space [PDF]

, 2002
summary:First we prove a general algebraic lemma. By applying the algebraic lemma we establish a general inequality involving the Ricci curvature of an arbitrary real hypersurface in a complex hyperbolic space.

Slant Submersions in Generalized Sasakian Space Forms and Some Optimal Inequalities

Axioms
This research examines key inequalities associated with the scalar and Ricci curvatures of slant submersions within generalized Sasakian space forms (GSSFs). We establish significant geometric constraints and conduct a detailed analysis of the conditions

A Qualitative Analysis of Social Indicators in Highly Polluting Sectors: The Challenge for Multifaceted Standards in Emerging Economies

Business Ethics, the Environment &Responsibility, Volume 35, Issue 3, Page 1931-1951, July 2026.
ABSTRACT The institutional current effort to regulate and increase the quantity and quality of sustainability information reported by companies is undeniable. However, the growing complexity of sustainability reporting standards creates isolated compartments for each major dimension of sustainability, leaving aside their interconnectedness and combined

Chen inequalities on warped product Legendrian submanifolds in Kenmotsu space forms and applications

Journal of Inequalities and Applications
In the current work, we study the geometry and topology of warped product Legendrian submanifolds in Kenmotsu space forms F 2 n + 1 ( ϵ ) $\mathbb{F}^{2n+1}(\epsilon )$ and derive the first Chen inequality, including extrinsic invariants such as the mean

Cohomogeneity‐one solitons in Laplacian flow: Local, smoothly‐closing and steady solitons

Journal of the London Mathematical Society, Volume 113, Issue 6, June 2026.
Abstract We initiate a systematic study of cohomogeneity‐one solitons in Bryant's Laplacian flow of closed G2$\text{G}_2$‐structures on a 7‐manifold, motivated by the problem of understanding finite‐time singularities of that flow. Here, we focus on solitons with symmetry groups Sp(2)${\rm Sp}(2)$ and SU(3)${\rm SU}(3)$; in both cases, we prove the ...

Curvature Invariants on Partially Totally Real Submanifolds in Complex Space Forms

Mathematics
Kähler manifolds are the most studied complex manifolds. A Kähler manifold with constant holomorphic sectional curvature is said to be a complex space form. There are special classes of submanifolds in Kähler manifolds. Recently, Poyraz et al.
