Pattabiraman pramank@gmail.com In this paper, we compute the formulae for the third Zagreb in-<br />dices and its coindices for two classes of graphs such as edge corona product graph, double graph and kth iterated double graph. 2018-01-10T00:00:00+01:00 Copyright (c) 2018 BULLETIN OF INTERNATIONAL MATHEMATICAL VIRTUAL INSTITUTE https://doisrpska.nub.rs/index.php/IMVI/article/view/4309 Extremal Graphs for the second multiplicative Zagreb Index 2018-01-10T10:30:20+01:00 Ali Ghalavand ali797ghalavand@gmail.com Ali Reza Ashra ashrafi@kashanu.ac.ir Ivan Gutman gutman@kg.ac.rs Let G be a graph with edge set E(G). The second multiplicative<br />Zagreb index of G is dened as 2(G) = Πuv2E(G)[degG(u) degG(v)], where degG(v) is the degree of the vertex v of G.
