Forcing isomorphism II

open access: yesJournal of Symbolic Logic, 1996
AbstractIf T has only countably many complete types, yet has a type of infinite multiplicity then there is a c.c.c. forcing notion such that, in any -generic extension of the universe, there are non-isomorphic models M1 and M2 of T that can be forced isomorphic by a c.c.c. forcing. We give examples showing that the hypothesis on the number of complete

Nonlinear maps preserving bi-skew Lie triple product on factor von Neumann algebras

open access: yesDemonstratio Mathematica
Let A $\mathcal{A}$ and B $\mathcal{B}$ be two factor von Neumann algebras with dimensions greater than 1. It is proved that if a bijective map Φ:A→B ${\Phi} : \mathcal{A}\to \mathcal{B}$ satisfies Φ([[A,B]⋄,C]⋄)=[[Φ(A),Φ(B)]⋄,Φ(C)]⋄ ${\Phi}\left ...

Clusters, Global Value Chains, and the Business Environment: A Hierarchy of Institutional Influence on Small and Medium Enterprise Sustainability

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Small and medium enterprises (SMEs) dominate the global business landscape, making their sustainability efforts crucial. Yet little is known about how institutional contexts shape these practices. Using Institutional Theory, we compare the influence of cluster membership (CM), global value chain (GVC) membership, and the organizational ...

Graph Isomorphism is not AC^0 reducible to Group Isomorphism [PDF]

open access: yes, 2010
We give a new upper bound for the Group and Quasigroup Isomorphism problems when the input structures are given explicitly by multiplication tables. We show that these problems can be computed by polynomial size nondeterministic circuits of unbounded fan-

Sectoral Heterogeneity in Corporate Biodiversity Disclosure: Evidence from Chinese Listed Companies Across Industries, 2001–2023

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT This study examines sectoral heterogeneity in corporate biodiversity disclosure (CBD) among Chinese listed firms over the period 2001–2023. Drawing on stakeholder, institutional, and resource dependency theories, it investigates how environmental exposure, ownership structures, and market dynamics influence biodiversity risk recognition and ...
