Abstract
In the present study, we introduce two new versions of Zagreb indices. Let ε(u) be the largest distance between u and anyother vertex v of G. These new topological indices are defined as *
M1 (G) =Σuv∈E(G) ε(u) + ε(v) and*2 uv E(G) M (G) ε(u)ε(v) ∈ = Σ . The goal of this paper is computing these new topological indices of a class of dendrimer graphs.
Keywords
