Abstract : The Weighted Padmakar–Ivan (PI) index of a connected, simple graph G is given by PIw(G) =∑e=(u,v)∈E(G)((dG(u) + dG(v))(|V (G)|− NG(e))), where NG(e) denotes the number of equidistant vertices of the edge e. In this paper, weighted PI index of tensor product and strong product of some graphs are obtained.
