WebJun 10, 2024 · A graph which admits a graceful labeling is called a graceful graph. In 1991, Gnanajothi [Citation6] introduced a labeling of Gcalled odd graceful labeling which is an injection ffrom the set of vertices V(G)to the set {0,1,2,…,2q−1}such that when each edge e=uvis assigned the label f(u)−f(v) , the resulting edge labels are {1,3,…,2q−1}. WebThere are many graphs that do not have edge even graceful labeling, so in this paper, we have extended the definition of edge even graceful labeling to r -edge even graceful labeling and strong r -edge even graceful labeling.
In graph theory, a graceful labeling of a graph with m edges is a labeling of its vertices with some subset of the integers from 0 to m inclusive, such that no two vertices share a label, and each edge is uniquely identified by the absolute difference between its endpoints, such that this magnitude lies between 1 … See more • In his original paper, Rosa proved that an Eulerian graph with number of edges m ≡ 1 (mod 4) or m ≡ 2 (mod 4) cannot be graceful. • Also in his original paper, Rosa proved that the cycle Cn is graceful if and only if n ≡ 0 (mod … See more • Edge-graceful labeling • List of conjectures See more • (K.
