Comparing the Multiplicative Zagreb Indices

Let G = (V, E) be a simple graph with n = vertical bar V vertical bar vertices and m = vertical bar E vertical bar edges. The first and the second Zagreb indices of G are defined as M-1(G) = Sigma(u is an element of v)d(u)(2) = Sigma(uv is an element of E)[d(u) + d(v)] and M-2(G) = Sigma(uv is an element of E)d(u)d(v), respectively, where d(u) denotes the degree of vertex u. We compare the multiplicative versions of these indices.
