چکیده

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.
