Isomorphism in strategic decision-making
… positively associated with industry dynamism - isomorphism was possibly used for risk reduction. No association with industry concentration was found: field structuration did not affect isomorphic behaviour. Pressures to imitate their peers, as perceived by participants, appeared unrelated to …

CONSTRUCTIONS AND ISOMORPHISM TYPES OF IMAGES
… proofs, either by hand or computer-based, of the isomorphism type of each image. In addition, we use Iwasawa's Lemma to prove that L<sub>2</sub>(13) over A<sub>5</sub>, L<sub>2</sub>(8) over D<sub>14</sub>, L<sub>2</sub>(13) over D<sub>14</sub>, L<sub>2</sub>(27) over 2D<sub>14</sub>, and …

Homormophic Images and their Isomorphism Types
… homomorphic images that we have discovered, the isomorphism type of each group is given. The homomorphic images discovered include Linear groups, Alternating groups, and two sporadic simple groups J<sub>1</sub> and J<sub>2</sub>X2 where J<sub>1</sub> is the smallest Janko group and J<sub>2</sub> …

Isomorphism classes of almost completely decomposable groups
In this thesis we investigate near-isomorphism classes and isomorphism classes of almost completely decomposable groups. In Chapter 2 we introduce the concept of almost completely decomposable groups and sum up their most important facts. A local group is an almost completely decomposable group …

Graph Isomorphism Algorithms Based on Trees and Paths.
… bounded algorithms are presented for testing isomorphism of two classes of graphs: the strongly regular graphs, which have been difficult for many previous isomorphism algorithms to process, and the compact graphs (graphs with diameter of 2 whose complements also have diameter of 2).The …

Isomorphism of uniform algebras on the 2-torus
<p>For \alpha a positive irrational, we consider the uniform subalgebra A_\alpha of C(T^2) consisting of those functions f satisfying \hat{f}(m,n)=0 whenever m+n\alpha<0. For positive irrationals \alpha, \beta, we determine when A_\alpha and A_\beta are isometrically isomorphic. Furthermore, we …

Supporting Device Mobility and State Distribution through Indirection, Topological Isomorphism and Evolutionary Algorithms
… we present a protocol that applies Topological Isomorphism to provide the continued balancing and reachability of data following partial network failure. This dissertation details the analysis of the proposed protocols and their evaluation through simulation. The results show that our proposed …

Algoritmi avanzati per il Subgraph Isomorphism, Motif Discovery, e Graph Embedding su reti complesse
I grafi sono strumenti potenti nelle scienze computazionali, in grado di modellare relazioni complesse in ambiti come la bioinformatica, l'analisi delle reti sociali e la chimica computazionale. Questa tesi affronta sfide fondamentali nell'analisi dei grafi, con particolare riferimento al problema …

Institutional pressures and decoupling in projects: The case of BIM level 2 and coercive isomorphism in the UK’s construction sector
… theorists would describe this as coercive isomorphism – encouraging firms across sectors to adopt the same practices. In the UK and many other countries, formal structures have been devised and imposed as part of these coercive efforts, including standardised processes for managing …

Metacyclic groups of odd order

A proof of Tsygan's formality conjecture for an arbitrary smooth manifold
… together with Kontsevich's formality quasi-isomorphism for Hochschild cochains of R((y1, . . . , yd)) and Shoikhet's formality quasi-isomorphism for Hochschild chains of R((y1, . . . , yd)) I prove Tsygan's formality conjecture for Hochschild chains of the algebra of functions on an …

The Discrete Hodge Star Operator and Poincaré Duality
… in proving and in realizing the Poincaré duality isomorphism (between cohomology and homology in complementary degrees) in a cellular setting without reference to a dual cell complex. More specifically, we provide a proof of this version of Poincaré duality over R via the simplicial discrete Hodge …

Corporate Narrative Disclosures in Saudi Arabia

Variations on the Theme of Higher Dimensional Weisfeiler-Leman Algorithms
… on graphs which over-approximates graph isomorphism. The latter, introduced in [30], are parametrised by a natural number and a set of prime numbers. By generalising the concept of coherent algebras to an arbitrary field, we show that the invertible map tests can be viewed as a …

Immersed Lagrangian Fillings of Legendrian Submanifolds via Generating Families
… Sabloff and Traynor proved that there is an isomorphism between the GF-cohomology groups of the Legendrian and the cohomology groups of any GF-compatible embedded Lagrangian filling. In this paper, we show that a similar isomorphism exists for immersed GF-compatible Lagrangian fillings; this …
