On reformulated Zagreb indices
Molecular Diversity, 2004Zagreb indices were reformulated in terms of the edge-degrees instead of the vertex-degrees as the original Zagreb indices. Three types of Zagreb indices were considered: original, modified and variable Zagreb indices. It is found that the optimum exponent of the variable reformulated Zagreb M2 index (v = -1/2) is identical with the exponent of the ...

Reformulated Zagreb indices of vertex F-join graphs
Journal of Discrete Mathematical Sciences and Cryptography, 2020The reformulated Zagreb index (or) RZ-invariant of a connected graph 𝒢 is defined as where d (a ) is the degree of a vertex a in 𝒢.

Some properties of the reformulated Zagreb indices
Journal of Mathematical Chemistry, 2010Miliević, Nikolić and Trinajstić (Mol Divers 8:393-399, 2004) proposed the reformed Zagreb indices in 2004. Now we give some properties for the reformed Zagreb indices.

\(F\)-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
