Cartesian product of hypergraphs: properties and algorithms [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2009
Cartesian products of graphs have been studied extensively since the 1960s. They make it possible to decrease the algorithmic complexity of problems by using the factorization of the product.

The majority coloring of the join and Cartesian product of some digraph [PDF]

open access: yesMATEC Web of Conferences, 2022
A majority coloring of a digraph is a vertex coloring such that for every vertex, the number of vertices with the same color in the out-neighborhood does not exceed half of its out-degree.

Product of Two Fuzzy Normed Spaces and its Completion [PDF]

open access: yesEngineering and Technology Journal, 2012
The aim of this paper is to prove that the Cartesian product of two complete fuzzy normed space is again a complete fuzzy normed space. Also to prove that the Cartesian product of two complete fuzzy inner product spaces is a complete fuzzy inner product ...

The Diagnosability of the Generalized Cartesian Product of Networks

open access: yesMathematics, 2023
Motivated by two typical ways to construct multiprocessor systems, matching composition networks and cycle composition networks, we generalize the definition of the Cartesian product of networks and consider the classical diagnosability of the ...

Fuzzy Bigroup from another Viewpoint

open access: yesFountain Journal of Natural and Applied Sciences (FUJNAS), 2016
In group theory, given two groups G and H, it is possible to construct a new group from the Cartesian product of G and H, G × H. With this as a motivation, we replicate this concept in fuzzy group algebra.

On Some Results in Fuzzy Length Space

open access: yesAl-Mustansiriyah Journal of Science, 2020
In this paper, depending on the notion of fuzzy length space we define the Cartesian product of two fuzzy length spaces. we proved that the Cartesian product of two fuzzy length spaces is a fuzzy length space.

Cubic Ideals of TM-algebras

open access: yesIbn Al-Haitham Journal for Pure and Applied Sciences, 2023
For the generality of fuzzy ideals in TM-algebra, a cubic ideal in this algebra has been studied, such as cubic ideals and cubic T-ideals. Some properties of these ideals are investigated.

On products in the coarse shape categories [PDF]

open access: yes, 2015
The paper is devoted to the study of coarse shape of Cartesian products of topological spaces. If the Cartesian product of two spaces $X$ and $Y$ admits an HPol-expansion, which is the Cartesian product of HPol-expansions of these spaces, then $X\times Y$
