Quasirecognition by prime graph of finite simple groups ${}^2D_n(3)$ [PDF]

open access: yesInternational Journal of Group Theory, 2014
Let $G$ be a finite group. In [Ghasemabadi et al., characterizations of the simple group ${}^2D_n(3)$ by prime graph and spectrum, Monatsh Math., 2011] it is proved that if $n$ is odd, then ${}^2D _n(3)$ is recognizable by prime graph and also by ...

Even-Odd Prime Harmonious Graphs [PDF]

open access: yesPandian Journal of Mathematical Sciences, 2022
The paper considers finite and undirected simple connected graphs. Usually, graph labeling is an assignment of integers to the vertices or edges in the method.

SOME CHEMICAL TOPOLOGICAL INDICES FOR THE COPRIME GRAPH OF THE INTEGERS MODULO GROUP

open access: yesBarekeng
This paper delves into the exploration of the coprime graph of a finite group G, a graph with vertices representing all group elements. Vertices x and y are considered adjacent in ΓG if their orders are relatively prime.

On some aspects of the generalized Petersen graph

open access: yesElectronic Journal of Graph Theory and Applications, 2017
Let $p \ge 3$ be a positive integer and let $k \in {1, 2, ..., p-1} \ \lfloor p/2 \rfloor$. The generalized Petersen graph GP(p,k) has its vertex and edge set as $V(GP(p, k)) = \{u_i : i \in Zp\} \cup \{u_i^\prime : i \in Z_p\}$ and $E(GP(p, k)) = \{u_i ...

Prime Cordial Graphs

open access: yes, 2017
Let be a graph. A prime cordial labeling of with vertex set is a bijection from to such that if each edge is assigned the label when gcd and otherwise, then the difference between the number of edges labeled with and the number of edges labeled with is at most . A graph which admits prime cordial labeling is called a prime cordial graph. In

Cubic semisymmetric graphs of order $ 40p $ [PDF]

open access: yesریاضی و جامعه
A simple graph $\Gamma$ is called semisymmetric if it is regular and edge-transitive but not vertex-transitive. A simple graph $\Gamma$ is called cubic whenever it is $ 3 $-regular.
