On Gorenstein log del Pezzo Surfaces
, 2001 In this paper, we first present the complete list of the singularity types of the Picard number one Gorenstein log del Pezzo surface and the number of the isomorphism classes with the given singularity type.

Isomorphism Classes of Uniform Groups
Rocky Mountain Journal of Mathematics, 2002 This paper concerns finite rank torsion-free Abelian groups which are extensions of a rigid completely decomposable group by a homocyclic \(p\)-group. The main results are a classification up to near isomorphism, and a count of the number of isomorphism classes in a given near isomorphism class.

Invariant Measure and Universality of the 2D Yang–Mills Langevin Dynamic
Communications on Pure and Applied Mathematics, EarlyView.ABSTRACT We prove that the Yang–Mills (YM) measure for the trivial principal bundle over the two‐dimensional torus, with any connected, compact structure group, is invariant for the associated renormalised Langevin dynamic. Our argument relies on a combination of regularity structures, lattice gauge‐fixing and Bourgain's method for invariant measures ...

On the connectedness of isomorphism classes
Manuscripta Mathematica, 1970 This paper is concerned with some topological properties of a notion of distance between normed linear spaces which is due to Banach and Mazur [1], We are interested in a pseudometric space associated naturally with this notion of distance, and our main result is that this pseudometric space is always pathwise connected.

Corporate Social Responsibility and Environmental Management, EarlyView.ABSTRACT This study explores how corporate environmental, social, and governance (ESG) performance affects equity misvaluation and how country‐level factors—national culture, environmental performance indicators, and world governance indicators (WGIs)—moderate the relationship between corporate ESG performance and misvaluation.

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 ...

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 ...

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 ...

Sustainability Disclosure and External Assurance of Reports in the Italian Agrifood Sector
Corporate Social Responsibility and Environmental Management, EarlyView.ABSTRACT The European Union introduced the Corporate Sustainability Reporting Directive (CSRD) with the aim of aligning the “walk”—the implementation of substantive sustainability practices—and the “talk”—their representation in sustainability reporting.

The Production of a Sustainability Reporting Norm in Spanish State‐Owned Enterprises
Corporate Social Responsibility and Environmental Management, EarlyView.ABSTRACT State‐owned enterprises (SOEs) are hybrid organizations that pursue social and economic goals and are expected to engage in sustainability reporting. Previous literature has shown limited attention to examining the process by which a norm in sustainability reporting has emerged among SOEs.
