The rainbow connection number of the enhanced power graph of a finite group

open access: yesElectronic Journal of Graph Theory and Applications, 2023
Let G be a finite group. The enhanced power graph ΓGe of G is the graph with vertex set G and two distinct vertices are adjacent if they generate a cyclic subgroup of G. In this article, we calculate the rainbow connection number of ΓGe.

MultiGSA: wind power prediction based on a multi-scale cross-graph network combined with an enhanced simple attention mechanism [PDF]

open access: yesScientific Reports
Wind power generation datasets are widely encountered in renewable energy systems because of their inherent periodicity, non-stationarity, and substantial noise.

On spectrum and energies of enhanced power graphs

open access: yesMathematics Open
The enhanced power graph [Formula: see text] of a group G is a simple graph with vertex set G and two distinct vertex are adjacent if and only if they belong to the same cyclic subgroup.

Perfect codes in power graphs of finite groups

open access: yesOpen Mathematics, 2017
The power graph of a finite group is the graph whose vertex set is the group, two distinct elements being adjacent if one is a power of the other. The enhanced power graph of a finite group is the graph whose vertex set consists of all elements of the ...

Between the enhanced power graph and the commuting graph

open access: yesJournal of Graph Theory, 2022
AbstractThe purpose of this note is to define a graph whose vertex set is a finite group , whose edge set is contained in that of the commuting graph of and contains the enhanced power graph of . We call this graph the deep commuting graph of . Two elements of are joined in the deep commuting graph if and only if their inverse images in every central ...

The cyclic graph (deleted enhanced power graph) of a direct product [PDF]

open access: yesInvolve, a Journal of Mathematics, 2021
Let $G$ be a finite group. Define a graph on the set $G^{\#} = G \setminus \{ 1 \}$ by declaring distinct elements $x,y\in G^{\#}$ to be adjacent if and only if $\langle x,y\rangle$ is cyclic. Denote this graph by $Δ(G)$. The graph $Δ(G)$ has appeared in the literature under the names cyclic graph and deleted enhanced power graph.

Enhanced power graphs of certain non-abelian groups

open access: yesDiscrete Mathematics, Algorithms and Applications, 2023
The enhanced power graph of a group [Formula: see text] is a simple undirected graph with vertex set [Formula: see text] and two vertices are adjacent if they belong to the same cyclic subgroup. In this paper, we obtain the Laplacian spectrum of the enhanced power graph of certain non-abelian groups, viz.

On the Structure of the Power Graph and the Enhanced Power Graph of a Group

open access: yesThe Electronic Journal of Combinatorics, 2017
Let $G$ be a group‎. ‎The power graph of $G$ is a graph with the vertex‎ ‎set $G$‎, ‎having an edge between two elements whenever one is a power of the other‎. ‎We characterize nilpotent groups whose power graphs have finite independence number‎. ‎For a bounded exponent group‎, ‎we prove its power graph is a perfect graph and we determine‎ ‎its clique ...
