Groups for which the noncommuting graph is a split graph [PDF]
International Journal of Group Theory, 2017 The noncommuting graph $nabla (G)$ of a group $G$ is a simple graph whose vertex set is the set of noncentral elements of $G$ and the edges of which are the ones connecting two noncommuting elements. We determine here, up to isomorphism, the structure of

Strategic Approaches to ESG Reporting: Analysing ESG Disclosures of Listed Companies
Business Strategy and the Environment, EarlyView.ABSTRACT This study adopts an exploratory approach to examine how firms communicate strategic orientation through ESG disclosures. Using a validated dictionary of exploration and exploitation language, we analyse 278 ESG reports from all UAE‐listed companies between 2020 and 2023, classifying ESG disclosures as exploration‐dominant, exploitation ...

Discrete Mathematics, 1984 A 4-isomorphism of two graphs G, G' is a bijection \(\phi:E(G)\to E(G')\) such that both \(\phi\) and \(\phi^{-1}\) preserve homeomorphs of \(K_ 4\). It is proved that each 4-isomorphism between 4-connected graphs is induced by a (usual) graph isomorphism.

Who Cares About Carbon Performance Strategy? Ownership Structure as a Driver for Carbon Performance
Business Strategy and the Environment, EarlyView.ABSTRACT This research aims to highlight the empirical, theoretical, and corporate governance arguments employed in the academic literature that examines ownership structure as a determinant of carbon performance—a key element in contemporary climate governance frameworks.

The Scheduling Model Based on Precedents
Цифровая трансформация, 2015 The paper presents an approach for university scheduling based on precedents. The model is based on the mathematical apparatus of the theory of graphs. The model uses the principles of finding and proof of the graph isomorphism. The process of finding of

Tits alternatives for graph products
, 2015 We discuss various types of Tits Alternative for subgroups of graph products of groups, and prove that, under some natural conditions, a graph product of groups satisfies a given form of Tits Alternative if and only if each vertex group satisfies this ...

Chemie Ingenieur Technik, EarlyView.This work explores generative AI for automated revision of Piping and Instrumentation Diagrams (P&IDs). We frame P&ID correction as a translation problem, converting attributed P&ID graphs into sequences and learning revisions with a transformer‐based model.

Structural Relationship of Isomorphic Graph and its Mapping to Hamming Distance [PDF]
EPJ Web of ConferencesMapping graph isomorphism to Hamming distance enables a simple yet effective approach to quantifying structural similarity. By encoding graphs as binary adjacency vectors—flattened from the upper triangle of the adjacency matrix—structural comparisons ...

On Isomorphisms of Vertex-transitive Graphs [PDF]
The Electronic Journal of Combinatorics, 2016 The isomorphism problem of Cayley graphs has been well studied in the literature, such as characterizations of CI (DCI)-graphs and CI (DCI)-groups. In this paper, we generalize these to vertex-transitive graphs and establish parallel results. Some interesting vertex-transitive graphs are given, including a first example of connected symmetric non ...
