Introduction to dominated edge chromatic number of a graph [PDF]

open access: yesOpuscula Mathematica, 2021
We introduce and study the dominated edge coloring of a graph. A dominated edge coloring of a graph \(G\), is a proper edge coloring of \(G\) such that each color class is dominated by at least one edge of \(G\).

The prime number graph [PDF]

open access: yesMathematics of Computation, 1979
Let p n {p_n} denote the nth prime. The prime number graph is the set of lattice points ( n , p n ) (n,{p_n}) , n = 1 , 2 , … n = 1,2 ...

Random Cyclic Triangle-Free Graphs of Prime Order

open access: yesJournal of Mathematics, 2021
Cyclic triangle-free process (CTFP) is the cyclic analog of the triangle-free process. It begins with an empty graph of order n and generates a cyclic graph of order n by iteratively adding parameters, chosen uniformly at random, subject to the ...

Recognition by degree prime-power graph and order of some characteristically simple groups [PDF]

open access: yesAUT Journal of Mathematics and Computing, 2021
In this paper, by the order of a group and triviality of $O_p(G)$ for some prime $p$, we give a new characterization for some characteristically simple groups. In fact, we prove that if {$p \in \{5, 17, 23, 37, 47, 73\}$ and $n \leqslant p$, where $n$ is

On unavoidable‐induced subgraphs in large prime graphs [PDF]

open access: yesJournal of Graph Theory, 2015
Chudnovsky, Kim, Oum, and Seymour recently established that any prime graph contains one of a short list of induced prime subgraphs [1]. In the present article, we reprove their theorem using many of the same ideas, but with the key model‐theoretic ...

Relatively Prime Detour Domination Number of Some Switching Graphs

open access: yesRatio Mathematica, 2023
In this paper, we introduce the concept of relatively prime detour domination number for switching graph. If a set S ⊆ V is a detour set, a dominating set with at least two elements, and has (deg(u), deg(v)) = 1 for each pair of vertices u and v, then it

On co-prime order graphs of finite abelian p-groups

open access: yesJournal of Mathematics and Computer Science, 2021
For a finite group G, the co-prime order graph Θ(G) of G is defined as the graph with vertex set G, the group itself, and two distinct vertices u, v in Θ(G) are adjacent if and only if gcd(o(u),o(v)) = 1 or a prime number.

Weakly Completely Prime Graph

open access: yesWasit Journal of 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 homomorphism is available in near rings, as well as the definition of homomorphism preserve vertex ...

Prime labelings on planar grid graphs

open access: yesTheory and Applications of Graphs, 2022
It is known that for any prime p and any integer n such that 1≤n≤p there exists a prime labeling on the pxn planar grid graph PpxPn.
