The isomorphism class of C0 is not Borel [PDF]
Israel Journal of Mathematics, 2019 We show that the class of all Banach spaces which are isomorphic to $ c_{0} $ is a complete analytic set with respect to the Effros Borel structure of separable Banach spaces. The proof employs a recent Bourgain-Delbaen construction by Argyros, Gasparis and Motakis.

Business Strategy and the Environment, EarlyView.ABSTRACT Manufacturing's transition to sustainable development depends on integrating green with lean under credible environmental policy and stakeholder engagement. Although benefits are well established, the literature underspecifies implementation barriers and their prioritisation. This study identifies, structures, and prioritises barriers to green–

Corporate Management of Environmental, Social, and Governance Ratings and Rating Divergence
Business Strategy and the Environment, EarlyView.ABSTRACT As environmental, social, and governance (ESG) ratings increasingly influence investment and corporate decision‐making, companies face growing pressure to manage their ESG performance strategically. This study examines how firms navigate the fragmented ESG rating landscape marked by significant agency divergence. Based on a multiple‐case study

Directed Graphs representing isomorphism classes of C-Hypergroupoids
Ratio Mathematica, 2012 We investigate the relation of directed graphs and hyperstructures by virtue of the graph hyperoperation. A new class of graphs arises in this way representing isomorphism classes of C-hypergroupoids and we present the 17 such graphs that correspond to ...

Commutative Chain Rings with Index of Nilpotency 5 and Residue Field
AxiomsThis paper gives a thorough characterization of chain rings with index of nilpotency 5 and residue field Fpm, where p represents a prime number, contributing valuable insights to the field of algebraic structures.

The Existence of Affine Structures on the Borel Subalgebra of Dimension 6
ComTech, 2021 The notion of affine structures arises in many fields of mathematics, including convex homogeneous cones, vertex algebras, and affine manifolds. On the other hand, it is well known that Frobenius Lie algebras correspond to the research of homogeneous ...

Business Strategy and the Environment, EarlyView.ABSTRACT This study assesses the degree of alignment with and eligibility to the EU Taxonomy of non‐financial firms and investigates its relationship with their Cost of Debt (CoD). The empirical analysis is based on a sample of 306 non‐financial firms listed on the Stoxx Europe 600 Index across 15 European countries. Taxonomy‐related data were manually

Business Strategy and the Environment, EarlyView.ABSTRACT The aim of this study is to examine the impact of corruption control, as a public institutional mechanism, on hazardous waste emissions of private sector entities. We also examine the extent to which Agenda 2030 moderates the relationship. We analyse data from the top 500 global companies.

Frobenius Local Rings of Length 5 and Index of Nilpotency 3
MathematicsThis paper investigates finite local non-chain rings associated by the well-known invariants p,n,m,l, and k, where p is a prime number. In particular, we provide a comprehensive characterization of Frobenius local rings of length l=5 and index of ...
