Integral Hodge conjecture for Fermat varieties [PDF]

Journal of Symbolic Computation, 2019
We describe an algorithm which verifies whether linear algebraic cycles of the Fermat variety generate the lattice of Hodge cycles. A computer implementation of this confirms the integral Hodge conjecture for quartic and quintic Fermat fourfolds. Our algorithm is based on computation of the list of elementary divisors of both the lattice of linear ...

Biomedical Kitchen Supports Student Transition to Higher Education Through Transdisciplinary Simulation

Biochemistry and Molecular Biology Education, EarlyView.
ABSTRACT The transition to university presents a significant challenge for undergraduate students in Biomedical Sciences, many of whom lack prior laboratory experience. This inexperience can create a discrepancy between students' perceived and actual competencies, leading to a self‐efficacy gap when compared to peers with previous laboratory exposure ...

What drives animal responses to high severity fire? The role of functional traits

Biological Reviews, EarlyView.
ABSTRACT Fire regimes are changing worldwide, with increases in the frequency, extent, and severity of fires posing growing risks to biodiversity. Fire severity – the degree of habitat alteration following fire – strongly influences both immediate survival and long‐term recovery of fauna.

Hodge Conjecture

This study investigates the Hodge Conjecture through a geometric and structural analysis of algebraic cycles, differential forms, and complex manifold topology. The framework focuses on the relationship between Hodge classes and algebraic varieties, examining whether specific cohomology classes can be represented through algebraic-cycle structures ...

Past and Future of Sustainability Indicator Research in Agribusiness: A Bibliometric and Forecasting Analysis

Business Strategy and the Environment, EarlyView.
ABSTRACT This study offers a forward‐looking assessment of sustainability indicator research in agribusiness by integrating bibliometric mapping with ARIMA‐based forecasting. Analysing 403 Scopus‐indexed articles, bibliographic‐coupling analysis identifies three contemporary thematic domains: Techno‐Managerial Sustainability, Systemic and ...

Stock Exchange ESG Disclosure Guidance and Corporate Carbon Mitigation: International Evidence

Business Strategy and the Environment, EarlyView.
ABSTRACT This study investigates the tangible impact of the adoption of environmental, social, and governance (ESG) disclosure guidance by stock exchanges on corporate carbon mitigation, focusing on six major frameworks: the Global Reporting Initiative (GRI), the Sustainability Accounting Standards Board (SASB), the Task Force on Climate Related ...

Strategic Implications of Mandatory ESG Assurance and Its Impact on Competitive Advantage: Evidence From European Market Reactions

Business Strategy and the Environment, EarlyView.
ABSTRACT The EU has recently introduced, for the first time, a market‐wide mandatory assurance requirement for sustainability reporting under the Corporate Sustainability Reporting Directive (CSRD). The directive mandates that affected firms obtain independent third‐party assurance for their ESG reports. This study examines the equity market's reaction

On the intermediate Jacobian of M5-branes

Journal of High Energy Physics
We study Euclidean M5-branes wrapping vertical divisors in elliptic Calabi-Yau fourfold compactifications of M/F-theory that admit a Sen limit. We construct these Calabi-Yau fourfolds as elliptic fibrations over coordinate flip O3/O7 orientifolds of ...

The Impact of Sustainability Audit Quality on Corporate Climate Change Performance: The Role of Governance Quality and Greenwashing

Business Strategy and the Environment, EarlyView.
ABSTRACT This study investigates how sustainability audit quality influences corporate climate change performance and examines the moderating roles of governance quality and greenwashing. Using panel regressions on 6140 firm‐year observations from 39 countries between 2008 and 2023, the findings reveal that higher sustainability audit quality is ...

Counterexample to the Hodge Conjecture

, 2006
We construct a K3 surface whose transcendental lattice has a self-isomorphism which is not a linear combination of self-isomorphisms over $\mathbb{Q}$ which preserve cup products up to nonzero multiples. Products of it with itself give candidates for counterexamples to the Hodge conjecture which may be of interest.
