Some cordial labeling for commuting graph of a subset of the dihedral group
Downloads
Abstract
The commuting graph of a group $G$, denoted by $\Gamma(G)$, is a graph whose vertices are all the elements of $G$ and two distinct vertices are joined by an edge whenever they commute. For an abelian group, the commuting graph becomes complete, so we shall consider the non abelian group for cordial labeling of commuting graph. In this paper, we examine sum cordial graph, signed product cordial graph, divisor cordial graph for the commuting graph of a subset $H$ of dihedral group $D_{2 n}$.
