There are various ways to label the graph vertices and edges. The graph labeling methods have their origin in the work of A. Rosa. Today there are a number of graph labeling techniques available to label a graph. For example Graceful labeling, Cordial labeling, Harmonious labelings etc. The graph labelings have got lot of applications also.
This book exclusively deals with 3- equitable labelings. It is not survey of 3-equitable graph families. It tells you about how the particular 3-equitable graph labelings of number of families are obtained. We show that Helms, Flower graphs, One point union of Helms Hn(k), K4(k), Snakes, Multiple Shells and so many other families as 3-equitable graphs.
