Symmetric duality for a class of multiobjective programming

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2000
We formulate a pair of symmetric dual nondifferentiable multiobjective programming and establish appropriate duality theorems. We also show that differentiable and nondifferentiable analogues of several pairs of symmetric dual problems can be obtained as

Dynamic Spillovers Between FinTech, Blockchain, and Green Finance: A Quantile Connectedness Approach

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT This paper explores how financial innovation and environmental sustainability intersect by analyzing spillovers between FinTech, blockchain energy use, and green finance. Using a Quantile Vector Autoregression (QVAR) framework, we examine weekly data from 2018 to 2024 across 11 digital, environmental, and macro‐financial indices.

Whose Sustainability Counts? Board Governance, ESG Ratings, and Sustainable Development Goals: Evidence on the ESG–SDG Wedge

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Institutional investors increasingly rely on ESG ratings to evaluate financially material sustainability risks, while governments promote corporate alignment with the United Nations Sustainable Development Goals (SDGs). Because these frameworks differ substantially in capital market salience and monitoring intensity, board oversight may not ...

ϵ-Henig Saddle Points and Duality of Set-Valued Optimization Problems in Real Linear Spaces

open access: yesThe Scientific World Journal, 2013
We study ϵ-Henig saddle points and duality of set-valued optimization problems in the setting of real linear spaces. Firstly, an equivalent characterization of ϵ-Henig saddle point of the Lagrangian set-valued map is obtained.

Digital Transformation of Supply Chains and Corporate Green Resilience: Evidence From China's Supply Chain Innovation and Application Pilot Cities

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Amid growing environmental pressures and sustainability challenges, understanding how institutional reforms enhance firms' ability to cope with green‐related disruptions is of substantial importance. Exploiting China's Supply Chain Innovation and Application Pilot Cities as a quasi‐natural experiment, this study investigates the impact of ...

Convergence Theorems for a Maximal Monotone Operator and a 𝑉-Strongly Nonexpansive Mapping in a Banach Space

open access: yesAbstract and Applied Analysis, 2010
Let E be a smooth Banach space with a norm ‖⋅‖. Let 𝑉(𝑥,𝑦)=‖𝑥‖2+‖𝑦‖2−2⟨𝑥,𝐽𝑦⟩ for any 𝑥,𝑦∈𝐸, where ⟨⋅,⋅⟩ stands for the duality pair and J is the normalized duality mapping.

Dual‐Plane Engineered GO‐Shielded GaN Core–Shell Nanowires for Cl−‐Resilient and Durable Seawater Splitting Photoelectrodes

open access: yesCarbon Energy, EarlyView.
The double‐bond phenomenon enables dual energy band mechanisms that enhance the efficiency of seawater splitting. Atomic interactions at the GO/GaN interface encompass various configurations, such as van der Waals interactions, covalent interactions, type‐II and Z‐scheme alignments, and chloride‐ion repulsion.

On duality theorems

open access: yesLinear Algebra and its Applications, 1981
AbstractThere are several examples in linear algebra and number theory of theorems which are formally similar to the well-known duality theorem of linear programming. The object of this paper is to present a general setting in which we can state and prove a simple criterion for such duality theorems to hold.

Vine copula knockoffs for variable selection in gene expression studies

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract Identifying clinical and genetic markers is essential for stratifying cancer patients by survival outcomes and guiding personalized treatment strategies. However, gene expression studies often involve high‐dimensional predictors with mixed data types and complex dependence, which complicates reliable variable selection.
