Properties of neutrosophic κ-ideals in subtraction semigroups G [PDF]

open access: yesNeutrosophic Sets and Systems, 2023
Our aim is to explore the idea of neutrosophic N-ideals in near-subtraction semigroups in this article and obtain some outcomes that are equivalent to them. We also illustrate the notion of a neutrosophic κ-intersection.

Quantum isomorphism is equivalent to equality of homomorphism counts from planar graphs [PDF]

open access: yesIEEE Annual Symposium on Foundations of Computer Science, 2019
Over 50 years ago, Lovász proved that two graphs are isomorphic if and only if they admit the same number of homomorphisms from any graph. Other equivalence relations on graphs, such as cospectrality or fractional isomorphism, can be characterized by ...

Weakly Completely Prime Graph

open access: yesWasit Journal for Pure Sciences, 2023
     In this paper, we presented a new properties of a weakly completely prime graph, where we added the algebraic properties in this graph and extracted from them some important theories and results, with the study of homomorphism in this graph when ...

A Study on Interval-Valued Fuzzy Graph with Application in Energy Industry Management

open access: yesDiscrete 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

K-algebras on quadripartitioned single valued neutrosophic sets [PDF]

open access: yesJournal of Fuzzy Extension and Applications, 2020
Quadripartitioned single valued neutrosophic (QSVN) set is a powerful structure where we have four components Truth-T, Falsity-F, Unknown-U and Contradiction-C.

Soft near-semirings

open access: yesAIMS Mathematics, 2020
Soft set theory was introduced by Molodtsov to deal with uncertainty. In this manuscript, we commence with the notion of soft near-semirings based on soft set theory.

Enumerating homomorphisms

open access: yesJournal of Computer and System Sciences, 2012
The homomorphism problem for relational structures is an abstract way of formulating constraint satisfaction problems (CSP) and various problems in database theory. The decision version of the homomorphism problem received a lot of attention in literature; in particular, the way the graph-theoretical structure of the variables and constraints ...

Towards a directed homotopy type theory [PDF]

open access: yes, 2018
In this paper, we present a directed homotopy type theory for reasoning synthetically about (higher) categories, directed homotopy theory, and its applications to concurrency. We specify a new `homomorphism' type former for Martin-L\"of type theory which

The undecidability of joint embedding and joint homomorphism for hereditary graph classes [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2019
We prove that the joint embedding property is undecidable for hereditary graph classes, via a reduction from the tiling problem. The proof is then adapted to show the undecidability of the joint homomorphism property as well.Comment: 17 pages; DMTCS ...
