Abstract :
In this paper first, we study the elementary properties of double graphs and then we present explicit formulas for a few topological indices on double graphs, i.e., of graphs that are the direct product of a simple graph G with the graph obtained by the complete graph K2 adding a loop to each vertex. Finally, we compute the eccentric connectivity index of the double of lexicographic product and complete sum of two graphs.
