• k – SUM AND n – SUM CORDIAL LABELING OF SOME GRAPHS
Abstract
Suppose G = (V (G), E (G)) is a graph with vertex set V (G) and edge set E (G). A vertex labeling f: V (G) ® {0, 1, 2…., k-1} where k is an integer, 1For each edge , assign the label (mod k). The map f is called a k-sum cordial labeling, if and, for and i, j Î{0, 1,2…,k-1} where and denote the number of vertices and edges respectively labeled with ( = 0, 1, 2,…, k-1). Any graph which satisfies k-sum cordial labeling is called a k-sum cordial graph. In this paper, we prove square graph of path is a k-sum cordial graph. Also we investigate some special graphs, are n+1 sum cordial graphs. Further we prove that the graph is a 3-sum cordial graph and Kn,n is a n - sum cordial graph.
