\(F\)-sums of graphs and their reformulated-Zagreb indices
2021Summary: The reformulated Zagreb index \(EM_1(G)\) of a simple graph \(G\) is defined as the sum of the terms \((d_u + d_v - 2)^2\) over all edges \(uv\) of \(G\). In this paper, we study the reformulated Zagreb indices for the \(F\)-sums of some special well-known graphs such as subdivision and total graph which is introduced by \textit{M. Eliasi} and
