Outer Independent Double Italian Domination of Some Graph Products

open access: yesTheory and Applications of Graphs, 2023
An outer independent double Italian dominating function on a graph $G$ is a function $f:V(G)\rightarrow\{0,1,2,3\}$ for which each vertex $x\in V(G)$ with $\color{red}{f(x)\in \{0,1\}}$ then $\sum_{y\in N[x]}f(y)\geqslant 3$ and vertices assigned $0 ...

Groupoids: Direct products, semidirect products and solvability

open access: yesAlgebra and Discrete Mathematics, 2022
We present some constructions of groupoids such as: direct product, semidirect product and give necessary and sufficient conditions for a groupoid to be embedded into a direct product of groupoids. Also, we establish necessary and sufficient conditions to determine when a semidirect product is direct.

Constant Degree Direct Product Testers with Small Soundness [PDF]

open access: yesIEEE Annual Symposium on Foundations of Computer Science
Let $X$ be a d-dimensional simplicial complex. A function $F: X(k)\rightarrow\{0,1\}^{k}$ is said to be a direct product function if there exists a function $f: x(1)\rightarrow\{0,1\}$ such that $F(\sigma)=(f(\sigma_{1}),\ \ldots,\ f(\sigma_{k}))$ for ...

Triangular Norm-Based Elements on Bounded Lattices

open access: yesAxioms, 2023
In this study, we introduce the notion of the T-irreducible element as a generalization of the notion of the meet-irreducible element in complete lattices. We derive some related properties of these elements and T-prime elements.

Principal arc analysis on direct product manifolds [PDF]

open access: yes, 2011
We propose a new approach to analyze data that naturally lie on manifolds. We focus on a special class of manifolds, called direct product manifolds, whose intrinsic dimension could be very high.

On the r-dynamic coloring of the direct product of a path with either a path or a cycle

open access: yesAIMS Mathematics, 2020
In this paper, we determine explicitly the r-dynamic chromatic number of the direct product of any given path with either a path or a cycle. Illustrative examples are shown for each one of the cases that are studied throughout the paper.

On the edge-balanced index sets of product graphs [PDF]

open access: yes, 2011
We characterize strongly edge regular product graphs and find the edge-balanced index sets of complete bipartite graphs without a perfect matching, the direct product $K_n\times K_2$.

Super Connected Direct Product of Graphs and Cycles

open access: yesAxioms, 2022
The topology of an interconnection network can be modeled by a graph G=(V(G),E(G)). The connectivity of graph G is a parameter used to measure the reliability of a corresponding network. The direct product is an important graph product. This paper mainly

New Concepts of Picture Fuzzy Graphs with Application

open access: yesMathematics, 2019
The picture fuzzy set is an efficient mathematical model to deal with uncertain real life problems, in which a intuitionistic fuzzy set may fail to reveal satisfactory results.
