EDGE DEGREE WEIGHT SUM OF PRODUCTS, SUM(JOIN) AND CORONA OF THREE GRAPHS
Let be the degree of a vertex u in a graph G. The weighted edge labeling is induced by summing the degrees of the end-verticesof the edge. For each edge the weight of e is The weight of a graph G, is defined by In [2, 4], the value of of sum(join) and standard products of two graphs are given. In this paper, we establish values of for direct product, Cartesian product, lexicographic product, strong product, join and corona of three graphs.
