The rst, second and modied rst multiplicative Zagreb indicesof a graph G are dened, respectively, as Π1(G) =Πu2V (G)dG(u)2, Π2(G) =Πuv2E(G) dG(u)dG(v)and Π 1(G) =Πuv2E(G)[dG(u) + dG(v)] where dG(w) is the degree of vertex w in G. In the present study, we obtain the expressions for Π1,Π 2 and Π 1 of generalized transformation graphs Gab
