Abstract :
The first general Zagreb index is defined as Mλ 1 (G) = Σ v∈V (G) dG(v) ^λ where λ ∈ R − {0, 1}. The case λ = 3, is called F-index. Similarly, reformulated first general Zagreb index is defined in terms of edge-drees as EMλ 1 (G) = Σ e∈E(G) dG(e) ^λ and the reformulated F-index is RF(G) = Σ e∈E(G) dG(e)^ 3 . In this paper, we compute the reformulated F-index for some graph operations.
