The allegory of isomorphism [PDF]
AVANT. The Journal of the Philosophical-Interdisciplinary Vanguard, 2019 Isomorphism has become a key concept for the analysis of representation in many contexts: perceptual experience, mental imagery, scientific theories, and visual artwork may all be described as standing in isomorphisms to their targets. Yet isomorphism is

Isomorphism problems of noncommutative deformations of type $D$ Kleinian singularities [PDF]
, 2009 We construct all possible noncommutative deformations of a Kleinian singularity ${\mathbb C}^2/\Gamma$ of type $D_n$ in terms of generators and relations, and solve the isomorphism problem for the associative algebras thus constructed.

Relaxations of Graph Isomorphism [PDF]
, 2017 We introduce a nonlocal game that captures and extends the notion of graph isomorphism. This game can be won in the classical case if and only if the two input graphs are isomorphic.

Theory of Computing Systems, 2005 We study the isomorphic implication problem for Boolean constraints. We show that this is a natural analog of the subgraph isomorphism problem. We prove that, depending on the set of constraints, this problem is in P, NP-complete, or NP-hard, coNP-hard, and in parallel access to NP.

A Study on Interval-Valued Fuzzy Graph with Application in Energy Industry Management
Discrete Dynamics in Nature and Society, 2022 In this paper, we define the concept of level graphs on interval-valued fuzzy graphs (IVFGs) and introduce the notions of α,β−α,β− homomorphism, isomorphism, weak isomorphism, and co-weak isomorphism of IVFGs by α,β− homomorphism. Also, an application of

Notion of Complex Spherical Dombi Fuzzy Graph and Its Application in Decision-Making Problems
IEEE Access, 2023 The complex spherical fuzzy graph (CSFG), which extends the concept of a spherical fuzzy graph (SFG), proves to be a more effective means of depicting relationships among diverse objects when these relationships are subject to uncertainty.

A Note on 4-Dimensional 2-Crossed Modules
Journal of New Theory, 2023 The study presents the direct product of two objects in the category of 4-dimensional 2-crossed modules. The structures of the domain, kernel, image, and codomain can be related using isomorphism theorems by defining the kernel and image of a morphism ...

Chinese Journal of Mechanical Engineering, 2021 Isomorphism detection is fundamental to the synthesis and innovative design of kinematic chains (KCs). The detection can be performed accurately by using the similarity of KCs.

Transformation Groups, 2022 AbstractIn a 1983 paper, the author has established a (decategorified) Satake equivalence for affine Hecke algebras. In this paper, we give new proofs for some results of that paper, one based on the theory ofJ-rings and one based on the known character formula for rational representations of a reductive group in positive, large characteristic. We also

On the history of the isomorphism problem of dynamical systems with special regard to von Neumann's contribution [PDF]
, 2011 This paper reviews some major episodes in the history of the spatial isomorphism problem of dynamical systems theory (ergodic theory). In particular, by analysing, both systematically and in historical context, a hitherto unpublished letter written in ...
