Graceful labeling of helm graph
Webedge receives a distinct positive integer label. A graph that can be gracefully labeled is called a graceful graph [11]. Examples of graceful graphs are shown in Figure 1. Interest in graceful labeling began with a conjecture by Kötzig-Ringel and a paper by Rosa in 1966 [11]. Many variations of graph labeling have been introduced in recent WebOne of the topics in graph theory is graph labeling. Graph labeling is an assignment of integers to the vertices or edges, or both, subject to certain conditions [2]. Graph …

WebJul 9, 2024 · A new type of labeling of a graph called an edge even graceful labeling has been introduced by Elsonbaty and Daoud . They introduced some path- and cycle … 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.
WebGracefully labeled graphs serve as models in a wide range of applications including coding theory and communication network addressing. The graceful labeling problem is to determine which graphs are graceful. It is conjectured (by Kotzig, Ringel and Rosa) that all trees are graceful.

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.
